Pillars of Eternity.
I was unsure between starting with a Paladin or a Cipher (read: psionic), but then I chose the former. While the powers of the Cipher are way more interesting, the "Shieldbearer of St. Elcga" is the ultimate diplomat, so I opted for that Paladin sub-class. Honesty, diplomacy and a shower of death to whoever tries to break the rules or doesn't want to resolve things as gentlemen! I always wanted to play a Lawful neutral-like Paladin, but D&D never allowed it.
I am just at the beginning, but for now it plays exactly like the good old Infinity Engine games. I'm loving the hand-drawn maps, that's for sure!
I'm also playing the first Unreal.
The first levels didn't really impress me, but the game design gets better and better as long as you progress. I like to re-paint Na Pali with Skaarj's (Nazi-lizardmen) entrails. The Flak cannon is by far the best brush, by the way; one of the most satisfying weapons I've ever used in any shooter.
