Well, I played DAH! for a few hours last night and I must say that it's one of those "well above average" type of games. (Like 8 out of 10)
Now keep it in mind that I'm talking about the Xbox version of the game... but the environments are simply gorgeous. The only real gripe that I have about the game is some of the dialogue that the humans have while you explore the levels with Crypto... other than that, I feel it's an enjoyable game.
(The new issue of Play magazine has a good review/pictures of this game. Just got done reading what they had to say during my lunch break at work today.)
