I've been playing this game a lot lately. I really enjoy it.
It needs a few tweaks first, so be sure to look up DSFix
so you can play the game at 1080p resolution (or higher). But once you've got that settled, it's time to start playing.
One of the great things about this game is that the combat is (generally) based more on skill than on grinding XP to level up your character. Few games make you feel like you have personally become more skilled and powerful like this one does such as when you find yourself literally running circles around an enemy so you can backstab them--thus killing them in one hit--instead of cautiously approaching with your shield up and getting killed anyway several times.
I recommend it (if you like this sort of thing).
Also be aware that the game uses Games for Windows Live (which has recently been put on life support by Microsoft) and thus the game is (soon to be) in the process of migrating from using GFWL services to using Steamworks
for cloud saves and achievements, etc. That's expected to happen sometime in December and may require some action on your part to migrate your saves and achievements.
