I'd heard good things about this game, first notably from a rather crude and popular interview review guy. But the game lives up to the hype. Interesting story, good characters and character animation, often catchy music (the music from the HQ area has been stuck in my head for days), and fairly good although sometimes frustrating game play.
My one complaint, if it can be made is that the intro arc is too short. The time BEFORE the main action gets started is all too brief, I would've liked to have known the characters a bit more before the crap hits the fan. And don't get me wrong, I talked to everyone, but I would've liked a little more talking, especially with the kids. Also it was never clear to me what the Janitor character was for, he didn't do much of anything.
This is well worth the price, and anyone even remotely interested should give it a go. You won't be dissapointed.
I would probably give it a 4.5 stars, but as there are no half-stars a 5 will have to do.
