You'll by far get more than 10 hours of Hyrule Warriors. If you're a Zelda fan, you won't only be playing it for a measly 10 hours. That's not an excuse to pick up the game.

Wasn't there just a 30% off Spring sale? SM3DW might have been one of the games. I'd check.

Out of the four games you highlighted, I've played 3D World, Hyrule Warriors, and Pikmin 3.

Super Mario 3D World is probably your best bet. I say this largely because it is the best platforming game in recent years and partially because I think it matches your desire for a meaty game. Though the game can be completed in about 10 or 15 hours, this would involve ignoring a huge amount of content. Some levels can be completely bypassed the first time going through the game, presumably so people don't get stuck on frustrating parts. About a third of the game's levels are unlocked after the Final Boss. There are four playable characters, one of which is unlocked after the final boss. Levels have collectable Stars and Stamps, some of which involve exploring levels in depth. This is easily a 40 Hour game if you want to beat the post-game.

My main warning would be that this is a very old-fashioned game in a way. Calling the story barebones is generous, and the focus is overwhelmingly on the gameplay and giving fun situations regardless of logic. I personally like the relatively pure experience, but it does turn some people off.

Hyrule Warriors is the most hit-or-miss of this trio. First, a lot of people find this style of gameplay repetitive. It is not a button masher, but can feel like one at first. The game also invests heavily on peoples' love of the Zelda series. You may know that Link is the guy in green, but if names like Ruto, Zant, Fi, and Impa are unfamiliar, you will likely miss out on the fan-service. Prior knowledge is never essential, but is highly rewarding.

That said, Hyrule Warriors is a Complete Package. The "Main Campaign," though only 10 hours or so, is more of a tour of what the game has to offer than the main course. you play it to unlock characters and get acquainted with the game before moving to Adventure Mode. Adventure Mode features a map with 128 spaces, each with challenges that demand specific feats from the player and reward you in various ways. Rewards include things like new weapons, upgrades, characters, and treasures, creating an MMO-like sensation of getting X so you can be strong enough to get Y and then acquire Z. This mode will take dozens of hours from your life, especially since you'll want to play some of these challenges multiple times. You may not get the A rank reward your first time, but even the base reward is useful, and you can go back later.

One last note is the DLC. Hyrule Warriors is odd for a Nintendo-published game in that it had loads of DLC after release. Ignoring the free stuff for a moment, which added three playable characters and a few other things, the DLC is a great deal. If you finish the campaign and like it, $20 will get you three new Adventure maps (each of which is another time-eater), new playable characters and weapons for existing characters, Challenges for the late game, a set of scenarios where you play as the Final Boss, and so on. It will more than double your playtime, and can keep you busy for months.

Pikmin 3 is, IMO, the best RTS in console history. It draws from the original Pikmin more than the sequel, but is definitely an improvement over both. You can juggle between a trio of commanders, the five Pikmin types used are distinct and well balanced (though Blue ones are a touch situational), and both the GamePad and Wiimote are better for controlling this game than the GameCube controller. There is an emphasis on foraging for food instead of the strict 30 day limit, which keeps the spirit of the original while encouraging more exploration and scouring over different environments. You can last anywhere from 3 to 99 days depending on how much food you find. The story requires players to obtain specific items and defeat certain foes, but how to do so is somewhat open-ended.

There was part of Pikmin 3 that I remeber playing that really captured what the game had to offer. I had one commander bringing Pikmin with him to bring some fruit back to the ship, a second back at base growing my dwindling population of Winged Pikmin, and a third exploring the area where the next objective was, destroying weak enemies along the way. I was swapping from one group to another every few seconds to make sure everything was going smoothly and ensure an efficient use of time. Around the time the third commander found what I had to do, the first group had returned to the base, and the groups at base met with the third to deal with a big scary enemy in the way.

Pikmin 3 has one big problem though: replay value. It is a 12 to 15 hour campaign with a couple of other things to do, but that's it. If longevity is a major priority, do not get Pikmin 3.

This is quite informative thank you, the part I bolded is pretty much what I want from games TBH, I don't want walls of text, loads of story or anything like that, I just like to say do this and go do it lol, although story is great, I am one of these people who if I have to invest in a story, I would invest from the first game and play all in order and that's something I really don't want to do :D

So far, my purchase order will be mario > hyrule > bayonetta 1 > pikmin 3 > bayonetta 2 

That is unless something else doesn't catch my eye :) I was really hoping for some discounts on the digital games, seeing as some of them have been out a long time!! But it looks like they keep there value, and I shall have to keep an eye out for sales and such! 

So, thought I would update everyone!

I bought mario, played a few hours with my friend coop and an hour on my own on a separate save, I am really enjoying it :) its quite challenging also in some places, but I think its just because I'm not used to playing these types of games, dark souls is easy to me, but rayman is hard lol figures eh :)

Get Super Mario 3D world, you won't be disappointed!

you'll get used to it. especially the stages that has the moving gameplay. it is a little bit challenging at first.  not sure if you wanted to have the 3 star and stamp each stage.  bayo 1 is inclusive from bayo 2 game.  so you are buying 2 games for the price of one.

someone suggested Donkey Kong Tropical Freeze, it is more difficult than Super Mario 3D World I think. 

save some moneey for xenoblade chronicles x. and try to look for Wii games as it is backwards compatible.  There are great JRPG games if you like that genre too.  try to check the VC games too if you want cheaper options. eShop have a ton of indie games. Shovel Knight is one of those great indie games.

Any good ones that dont use motion? what put me off the wii is the motion, I really don't want to sit upright in view of my sense bar waving my arms around :( I like to lazy back and not move while playing games :D

SM3DW would be the ideal game for you, just make sure you collect those stamps and green stars. They're very fun to collect, some are hidden well!

And get DKC: TF. It's the best 2D platformer on the system and of the generation.

Have you played WW yet? If so get WW HD as well!

edit: you did, but get it anyway. xD

You would find that many games improve with motion controls a lot. There are a lot of games that you don't have to wave your arms all the time haha. If you didn't play Metroid Prime I recommend you to buy the trilogy. Motion controls in that game work wonderful, they are much more responsible than sticks and I assure you they are not tiresome (I am a lazy person too :P ). By the way, 3DWorld is the best WiiU game for me, so I'm glad you decided for Mario. It could be very challenging if you find all the 3 green stars and stamps. You'll see when you play the final levels :P. I spent almost 30 hours in that game to achieve 100%. Hyrule Warriors is an amazing game (vastly underrated). It's very fun, and you can spend perfectly more than one hundred hours.
