I absolutely loved this game. I'd say it might even be the best I played this year. A lot of game devs need to be locked into a room and study this thing to death for how to do branching dialogue in a believable manner. The game had fantastic voice-acting and writing, and some of the characters just crawl under your skin. I think TTG deserves a lot of kudos as well, because I don't think the game would have been half as impactful without the excellent model animation, particularly the faces. Well, ok, I kept looking at Omid and wishing the pop-eyed SOB would blink once in awhile, but that's just nitpicking.
To those who say your choices didn't matter, because it didn't change the game...
First of all, on first playthrough, I had no idea what decisions of mine "really" changed the story. I knew just from a project scope level that they couldn't possibly produce a whole lot in the way of branching storylines, but it wasn't until I started a second playthrough that I began to see all the way behind the curtain to see the "rails". As far as I am concerned, they maintained an illusion of choice extremely well all the way throughout.
Second, this game wasn't about decisions affecting the story. Its about how those decisions, made under pressure with no real right or wrong answer, affected you. I've never played a more intense game in that regards.
Gamer4Life, I suspect she will be though... to me the final cut scene of her in the field was more "cliffhanger" than "closure".
