[quote name='iguss']Does anyone know when Lost the game takes place, in terms of the four seasons?[/quote]
From what I've read it seems to span across the first two seasons, but includes locations and characters from season 3 as well. The logic behind this is that you play as a "new" passenger from 815, so places you go and things you do may not have been discovered by the rest of the main characters yet. I know you interact with the main characters though, but whether new information is revealed about what's going on, I have no idea.
It's possible the game could suck (but honestly, that's still possible for the show as well...depending on the ending). I just know I've invested this much time into the franchise, I might as well stick with it, and hope it all makes sense in the end.
