Finally finished it for the first time. (and maybe the last)
I guess i will have to make some kind of review later.
In short, i have some mixed feelings about it. The core of the gameplay seems all about fighting and riddles, and less about story & character interaction, which doesn't fit well with my taste and the time i consent to throw in those. On the other hand, it has some tone, plot point, and game mechanics design that i think would benefit to some other games.
Strangelly, i am currently more interested to do a little more post-end playing (not much since i used a playthrough for most of the game), than playing Wasteland 2 right after it.
IMO, the game's lore seems to work more on the imagination than in the actual delivery. You have an atmosphere, some pictures, a few description, and the locations layout, and you let your brain fill the blanks... A kind of design that i often despise in other games, but somehow works there, as the whole point is to throw you in the middle of that world and let you deal with it.
