I really liked this game.
I have been reading The Walking Dead, and also watched the TV series, and I think the game is pretty faithful to the idea of the comic. It focuses on people interaction and the zombies are just some kind of prop to trigger people into these interactions. If you have read the comic you have seen the dehumanization of Rick, Carl and the rest of the group as numbers go by.
My opinions are pretty much the same as NickyNyce. I loved the game but felt it lacked some serious puzzles. The radio puzzle is a joke.
Having played Jurassic Park, I must disagree with ProgZmax, this is nothing like JP. It's not some smash-buttons-at-the-right-time thing, it's like a soften up point n' click.
As for my choices:
I might play the game and choose all the opposite actions, just to see what happens.
I'm just really curious to see how my actions will influence the game in the future, this is one of the best thing about TWD.
