i picked it up, like it so far.
nice mechanics as far as gameplay, graphics are not great but dont take away from the experience. and in reality, what from bethesda has had jaw dropping graphics? fallouts, not so much, elder scrolls, not so much, even skyrim wasnt the best.
but it plays similar to bioshock but has more of a free roam style. You do missions, but inside the missions, there as side objective (small missions). Each mission seems to be comprised of a few decent sized areas and a big area.
i say go out and get it, fun game to play.
