I know perfectly well how comparisons work mate you seem to be the one struggling as reading your reply it's clear you didn't even read some of the points properly, Splatoon has an unranked mode for casual play your level doesn't measure your skill only your number of games with the game hence why it only unlocks gear, rank is measured by letters S, A, B etc... the fact you don't even know this makes me question your experience with the game altogether. You even need to get to level 5 or so to start playing competitive modes unless they patched that out so newcomers play a number of casual bouts before they play higher skilled players so by default your match making argument is null and void as what you're refering to is not competitive match making you're just playing other casuals.

Competitive means you are in competition with other players.  It has nothing to do with whether you are ranked or unranked.  Unless I'm playing single player, I am playing a competitive game in every mode.  Don't blame me because you are not using the right words.

The game actually measures your skill on both modes because you are awarded extra points for wins and based on individual performance.  Even if it was measuring only number of games (it's not) we can logically expect a person at level 50 who has played the game a lot to be better than a person at level 15.  People playing unranked are not necessarily casuals. They could just be people that prefer splatfest to the other modes of the game.  

Under your own logic playing Mario Kart with other people trying to win would be stressful for a casual because you're arguing people would get discouraged in a 4v4 because the is another team trying to win, you may as well argue Smash is the same because the other player is trying to win. You've not given any concrete arguments why Splatoon is more complex tbh.

No.  I'm not even sure where we got this because I said absolutely nothing about anything being stressful.  So, I don't know how you came to any conclusion about what is stressful according to my logic.  You're literally pulling things out of thin air.

The 2D Mario part is were I know you're not reading the post properly, it was brought up to highlight how simple games sell better to casual players and yes having larger more complex worlds is more complex, Splatoon are small simple arenas that you spread ink in that you can use your squid ability in you simply run around and fire your weapon and don't have to worry about how many kills you rack up. A large open world Mario would not only require more use and knowledge of the move set than Splatoon does but needs a more avid approach to progress compared to shooting ink around a small arena.

No, I'm reading it properly, I assure you.  But, you again don't know how to compare.  You can't just cherry pick one aspect and ignore everything else.  If Mario Odyssey is more complex in one area (larger worlds) that doesn't mean it's more complex overall, and that's literally the only argument you've brought.

Splatoon requires battling against other humans with human brains who are capable of spontaneously adapting to you and creating new strategies.  Mario involves fighting against enemies with limited set patterns.  Splatoon is objectively more complex in this regard.  Unless you would like to tell me that goomba AI is comparable to the human brain.

Enemies in Mario are generally put in your direct line of sight.  Splatoon enemies can strike you from anywhere and any angle.  Splatoon is objectively more complex in this regard.  Needing to be constantly aware of your surroundings in a 360 degree radius is far more compex than dealing mostly with things in your direct line of sight.

Splatoon enemies can attack you from half a level away or more.  Mario enemies don't.  This means you have to be constantly aware of the bulk of the level, which is again objectively more complex.

Splatoon requires constant manipulation of 2 physical joysticks, and one virtual joystick (gyro).  Mario requires one joystick.  Splatoon is objectively more complex here.

Splatoon requires 6 primary buttons (fire primary, fire sub, jump, transform, special weapon, center) and 5 secondary buttons (map, warp buttons).  Mario requires 3 primary buttons (crouch, jump, attack) and 4 secodary buttons (camera).  Some games may require slightly more or less.  Splatoon is objectively more complex.  

Enemies in Mario attack when approached.  If you stand still without an enemy in your direct vicinity, you will be almost always safe.  You have a virtually unlimited amount of time to formulate a plan of action.  Splatoon enemies will come after you.  Splatoon is objectively more complex in this regard.  

Enemies in Mario generally will not kill very quickly, and will take a minimum of 3 hits in the 64 style.  Several weapons in Splatoon will kill you in one hit, and virtually every weapon will kill you within a second of direct fire.  Splatoon is objectively more challenging and complex here.

And while you can just go around spraying ink haphazardly, we're assuming people want games they can be successful at.  Spraying ink with no regard for enemies is a nearly guaranteed way to lose.

This is how I know you're somewhat out of your league here someone being competitive is different from someone playing casually for fun, Ranked is there for competitive play i.e. people who want to master their skill and be the best, the system matches these players by rank  and constantly assesses their skill, in unranked the game doesn't measure your skill it just counts the number of games you're playing and gives you points to unlock more gear. I will blame you here because the term I used is correct when discussing multiplayer games and only someone with no idea about the concept of competitive play can even misunderstand that.

You're arguing that the presence of other people trying to win is not casual friendly so under that logic games like MK, Smash, COD, FIFA etc... aren't casual friendly but as we can see from the majority who buy these games you're quite wrong on this aspect.

Not cherry picking that accusation falls more to yourself and your flawed reasoning about Splatoon, Odyssey will no doubt have bigger worlds, more puzzles, more moves (we already know this one), more worlds which are likely to require specific approaches, likely many more mechanics etc... This requires a more avid approach then Splatoon's very simple to get into gameplay which is universal across all its modes. You're busy harping on about how comparisons  are not right what not to cover the flaws in your argument and I'll highlight some of them.

Using two analogues - Guess what people have been using them since the PS1, Mario will require it for the Camera so a contradiction here in your argument, Gyro is also option to use and one that is more casual friendly as well.

Enemies - Splatoon you only have four enemies to battle against while team mates help you out so that balances out things, in casual play the enemies arer also other casual players as well.

Button usage - Mario requires more then 3 buttons and some actions aren't as easy for casuals to master like wall jumps to get to specific platforms and so on, again this balances it self out and tbh Splatoon edges this one because the actions to enjoy the game are dead simple 3D Mario games have had micro tricks that have generally been trickier to handle.

Death - Dying in Splatoon is not punishing unlike in 3D Mario, the former you just respawn and jump to a teamate to continue on the latter has often meant you have to redo the task or level and in Mario the are things that have killed the player in one hit as well like platforming sections, certain enemies, failing specific tasks etc... Once you get into it you start to realize it's not as casual as you think.

Spraying ink aimlessly can make you lose yeah but so can simply running around just trying to rack up kills, someone can run around firing ink and win without a single kill whicl the person with 15 kills still loses. It's easy to understand just cover the arena in ink and just as easy to do.

I will say Splatoon 2 just to be opposite, lol. Seriously though I do think Splatoon 2 has potential to explode in Japan and become one of the biggest franchises there.

Over 3 million in Japan alone is a very real possibility.

I'm not sure. If people view splatoon 2 as more like Splatoon 1.5, then Odyssey. Then again, even if Spltwoon is viewed as a true sequel worth buying, I think people have wanted a 3d exploration mario game since 64/sunshine, so who knows.

Well we already know that Splatoon is biggest new IP in Japan from Resident Evil think. Splatoon2 alone can do at least 3m in Japan alone, dont forget that in Japan Splatoon sold around 1.4m on instal base of 3.3m. Splatoon available in full handheld mode will be much more popular than Splatoon just for home console play was.

It really doesn't matter how people see Splatoon 2, fact is that Wii U instal base was very small (you will have tons of people who didn't had Wii U) and that Splatoon 2 can be played in full handheld mode also.

I think that Splatoon 2 has potential to become one of the best selling games on WiiU.

Mario Oddisey will sell very well, though, but I think Splatoon 2 will do better.

I don't really play either series, but I think Mario will smash it in the ground.

Mario will destory it in sales......3D world wasnt the Mario game peolle actually wanted.....this is a more mainline entry
