Red Steel 2?

Isn't Red Steel Nintendo exclusive, though?

Bayonetta 2?

Uncharted 2: Among Thieves

I don't see anything about owning games in the rules... in fact, I have a few arcade games in my list.

#22
Super Mario Galaxy 2 (Wii, 2010)
guessed by mZuzek

Before I played Super Mario Galaxy 2, I was skeptical that it could match the original Super Mario Galaxy, one of the best games of the seventh generation. Several weeks and 242 stars later, I was happy to be proven wrong. Galaxy 2 is nothing short of a masterpiece, a game that, in the words of Edge Magazine "rolls [the genre] up and locks it away." The sheer imagination on display in the game is mind-boggling. It packs more ideas and mechanics into individual levels than some games do in their entirety. Super Mario Galaxy 2 might not be as revolutionary is its predecessor, but it's every bit as beautiful, creative, and fun.

Shit's really slowed down in this thread. Does everyone else have final exams too?

24: Super Mario Galaxy 2. Lacked the wow factor of the first game, but had all of the excellence under the hood, and more in terms of the green stars.

23: Pokemon Red/Blue: What started it all, wins points for nostalgia, loses points for being quite crude compared to the games that followed, still second-highest from this franchise on my list.

22: Monster Hunter Tri/U: Hundreds and hundreds of hours spent on these two games, which basically count as the same game as the one is just up-ressing the other and adding an extra layer of difficulty and a few more monsters.

#27 - Super Mario Galaxy

If asked to sum up this game in one word, I would have to go with: "Magical". This Mario adventure was bright, colorful, beautiful, inspired, creative, not all that challenging but always entertaining. Using the underpowered Wii to its full extent, this game proved art direction could do wonders. The controls are what you expect from a Mario game, tight and responsive, the worlds are diverse and a blast to explore. 

#26 - Donkey Kong Country

After the horrible Donkey Kong Jr. Math game released in 1983, poor DK was shunned for more than a decade but Rare sought out to bring him back and boy did they succeed! Outfitted with a cool new sidekick and a host of animal friends and top of the line graphics Donkey Kong Country was intriguing even before playing it. 

And then once you got to experience the game, you quickly realized this game wasn't all looks, it was a superbly crafted platformer with some real challenge and a ton of bonuses to search for that increased replayability. Truly a SNES gem.

#25 - The Legend of Zelda: The Wind Waker HD

I really liked the original but it had some flaws that kept it from reaching Top 50 status before but when the HD version came not only did Nintendo put a new coat of paint over the already incredible looking Wind Waker but they managed to fix pretty much all of the annoying points of the original (I'd still have taken a dungeon or two over the triforce fetch quest but I'm being demanding). 

This adventure feature the most charming version of Link, with his toon version showing fun facial expression through the game's story and gameplay. The dungeons are well thought out and fun (but too few!) and you get to stab Ganondorf in the head with your Master Sword!
