The 'sandbox gaming' trend every developer seems to be stuck on, it's turning into a stupid gimmick. Seriously, I like a good story, something with value and creativity to it. Too much freedom leads to boredom (Imagine if they made Half Life sandbox?), plus sandbox gaming prevents canon sequels, or for that matters, makes them preposterous (remember the fail that was Deus Ex 2, especially compared to the sheer awesome of the first game? The developers couldn't figure out how to start the game canon, so they just figured that ALL of the endings from the original game happened.)
