Crusader Kings 2 is hardly impenetrable. I thought so too for my first hour. You just have to have a little patience. Now after 40 hours put in it's starting to actually feel too shallow for me.
It took me a while to get into it, and I think it's ok, but EU is their best series (HOI would be for some folks, I didn't care for it though)
Thinking about getting:
Batman: Arkham City - Game of the Year Edition
Civilization IV: Complete
Mark of the Ninja
Hotline Miami
Which one would you guys recommend?
Civ IV complete is best Civ. GalCiv 2 on the flash deal is worth it as well- still Stardock's best game (Fallen Enchantress is close but not there yet)
