Well, for me, I won't say that I have more fun, but a different kind of fun :P

A casual game is a niche game that a very few select gamers play because they are wanting to separate themselves from the crowd by calling themselves absurd laughable terms such as "hardcore gamers" and playing games that would kill the entire video game industry because they do not appeal to a mass audience to achieve the sales in order to cover the costs and create a profit for new games. This phenomenon has grown as those younger than 18 years old have flooded the forums with their "I want to be unique" mood. The only other kids who act like this are the little teenage punks who change their hair color every other week and dress in the most horrid way with nose rings and whatnot because they are seeking attention on their looks alone, not their smarts, talents, ambitions, and dreams.

For example,  these casual gamers will say Modern Warfare 2 is a "Hardcore game."

I ask how is Modern Warfare 2 hardcore in comparison to a game such as Doom?

Doom never had casual crutches such as killstreaks, killcams, and deathstreaks. If anything the addition of these three is a casual crutch for the mass audience because without them they would not perform a third as good as they do with them. Doom, if I remember correctly, also did not have the crutch of a radar where your enemies showed up  as red blips.

Playing Doom, you had your weapon and it was a constant guess as to where the opposing players were and a fairly equal fight based entirely on hand-to-eye coordination and reflexes in headshotting or killing your enemy before they took you down.

So in comparison to an old school shooter like Doom or even Unreal Tournament, the entire Modern Warfare series is a dumbed down, casual series for a mass of players who would suck it up if they did not have their radar, killstreaks, deathstreaks, and killcams in order to learn player behavior so that they can actually have a positive K/D ratio.

I always think of 'casual' and 'hardcore' is a way of playing a game rather than describing a game, for example my Mum loves playing art style picopict, what many would consider a 'casual game' but plays it in a very hardcore manner.

There is definitely a divide within the industry on the matter.  At my 6th form college, most gamers I would consider 'casual' play fitness games, FPS and racing games.  The people I consider hardcore generally play platformers and jrpgs.  But that is a massive generalisation.

A casual game is a game that is suited to be played only now and then and in rather short sessions. Whenever you want to have a little fun time, you can start a casual game, you're right in the middle of the action, you have fun for a few minutes and afterwards it's no problem to not play the game for weeks because a single gaming session is usually self-contained.

This leads to casual games usually having the following characteristics:

- the rules and mechanics of the game are very easy to understand, though eventually hard to master. You do not need half an hour of tutorial levels to understand even the basic actions etc., the game is instantly accessible

- a single round of the game usually only takes a few minutes and is self-contained - unlike for example a game like Zelda, where you make slow progess, the games takes dozens of hours, you do not play through in a single session. This also leads to casual games not having much of a story and not having a clear end.

I consider Bejeweled a perfect example of a casual game. The gameplay is understood within five seconds, and whenever you need to waste a few minutes (for example because you're waiting for the bus) you can enjoy a full game of it within that time.

So I'd say all minigames (and minigame collections) are casual games, but it's not necessarily the other way around. For example I'd consider Singstar and Guitar Hero casual games, but not necessarily minigames.

A casual game should be any game that you can pick up and play for a few minutes at a time where there's no real need to put a lot of time in to the game to see all that there is to see (so no games that require you to put hour after hour in to progress within the story, such as a Zelda or a Final Fantasy). It doesn't matter if it's a few minutes of MW2 online, or a few minutes of Doodle Jump, both would be casual games by its true definition.

That isn't what casual means these days though...

i came to the conclusion rolstoppable its clearly and internet hype bot for nintendo products.

You said it. Retarted games for retarded people.

The videogame industry takes most boardgames and cardgames and shoves them in the "casual" area.  This is why I say it is ironic.  The videogame industry doesn't consider it "hardcore" at all, eventhough it is very deep.

You see chess pop up on "casual" game sites:

Google search for chess and casual games together

I believe when the action genre of videogame absorbed adventure games, it led to the modern trend in videogames we see in the blockbusters.  The focus on story has gotten elevated, to the extend most of the single-player sided games can be seen as interactive fiction, more than traditional games.  The multiplayer vs side still holds onto the traditional definition of games.

And here is the info on Civilization:

So, there is validity to the original argument, and I do stand a bit corrected.

Want to get a good focal point on what a "casual" game is?  Well, think about what you see when you see an arcade game.  Look at what goes into making an arcade game that will generate revenue, and you get a good focal point on what works for "casual" gaming.

Watch this video:

Nintendo is masters at these games, by the way.  A reason for this, is they had some roots of success in the arcades.
