Hmm... I'll mention 2, not just 1.
Crysis (PC). What was wrong with Crysis? The fact that it was a graphics whore and was designed that way without many levels of optimization, making it a 'standard' or ego-stroking based on how fast you can run the game. Doesn't help that the graphical settings don't actually help matters by barely changing anything. The gameplay is just your generic walk-around-and-get-headshots and you won't have time or ammunition to play with physics. I heard it comes with a Sandbox mode, even in the demo, but I've yet to figure out how to get to that.
Star Wars: Lethal Alliance (DS): This game is just plain bad. Awkward controls combined with bad music (the DS can do far better, see Trauma Center 2), mandatory puzzles which have little to no explanation whatsoever in the game's manual, PS1-level graphics and the like pretty much make this game a disappointment. That's right, I said this game had PS1-looking graphics. There's just no style here, it'd be more at home as a 1st-2nd gen PS1 Star Wars game.
