Yes I've played Episode 1 and 2.
I wouldn't really say there's much similarity to those games (or that game...is it considered one game?). There are choices to be made, and the ending can be slightly altered, but it's more a case of the game telling you what to do, and then punishing you for it.
It's pretty much linear. You do what you think is right at the time, and then it bites you in the ass later.
