How quickly does a game have to hook you before you put it away?

It varies a lot on a game to game basis. If the controls are bad, the game needs other redeeming features, and lots of them! Some times I'm just having trouble getting into a game, but I'll give more chances to grip me if it's gotten critical acclaim or forum hype.

same here, but i try to do a lot of research on my games so i havent experienced to much of this, this gen.  didnt like bladestorm, but i give it about an hour before giving up and the demo's of ratchet and clank didnt same to appeal to me tried them for about 15mins.
