I only got in a couple of hours last night, but I can already tell this is going to be a game I will love.
I did expect a bit more polish, though. The menus in particular are a bit unwieldy, and the texture resolution/detail is quite low in many areas, resulting in some really ugly looking stuff.
The one thing that is near unforgivable is how they handle death. Maybe it's just me, but I had figured the game autosaved constantly or worked like an MMORPG and I was sure in for a rude awakening when I died and lost a bunch of progress. I thought I would simply resurrect in town or at a checkpoint, but instead I actually have to load my last save. Very weak. It's even worse since manually saving on the PS3 seems to take something like 30 seconds each time.
Anyway, I think it's a cool game, but damn I sure wish there was a PC version. Graphical quality and performance issues aside, simple things like being able to hit "M" for the map, "J" for quests, "I" for the inventory, and "F5" for a quick save would make this so much more playable.
