Braid is a Puzzle/Platformer and is a fun and challenging game. Braids lasting appeal is all up to have you play it, if you want to get a 100% Braid can last you a good while but the only problem is that after beating the final puzzle there isn't anything to do. The soundtrack for Braid is so good that they released a soundtrack on iTunes, which by the way I bought. The story is the same old story the princess has been kidnapped and you have to save her. It's the only motivation you have to play the game. Braid's graphics are 2D but very stylist. As I said before the gameplay is fun and challenging, think Mario but much puzzle-er. It's kinda sad there isn't multiplayer because it would have been cool to run through the levels co-op style and it would have made the for some crazy ass puzzles. Braid is a great game and is a great buy for anyone looking for a good XBLA game. At only $15 or 1200 MSP Braid is better then some $50 or $60 games.
