I probably got the best case scenario with Rayman. Playing it with a younger person who actually enjoys the pointless touch screen/gyro stuff, asI never had to deal with it, and just got to enjoy the strong platforming side.
I know yoshi looks amazing, I certainly wouldn't disagree there, but the collectables crap which is at the core of the game is something fundamental to the game. A few things is OK, but they always go too far for my liking in Yoshi games.
Well... for 3DS the only Nintendo published game I bought this entire year, played enough and enjoyed was Majoras Mask, which was great. Now, I'm expecting Triforce heroes as a christmas present, and Mario & Luigi is out soon, which is probably going to be solid. But so far, again, the only Nintendo published game I can recommend so far is Majora, which is a port of an old N64 game. I got codename steam during one of the bargain bin sales but then never touched it. And I can't actually think of another Nintendo published 3DS game from this year, so even if I'm missing something, I guess I didn't enjoy it.
