I just got the first one, and I love it so far. Which suprises me a bit, seeing as I couldn't get into the other action RPGs I've tried (Bioshock and Fallout 3). Usually me playing those kinds of games goes like this:
Phase 1: "I have no idea what I'm doing or where I'm supposed to go next."
Phase 2: Need to go into area swarming with enemies; only have 2 pistol rounds. Spend hours trying to get weapons and ammo.
Phase 3: Finally move on, get slaughtered. Trade in at Gamestop.
