I've also been playing a game called Dark Souls on my Xbox360 (it's a console exclusive) and it's been an absolute thrill ride from the moment I started. It's a Fantasy RPG game set in a dying world that has fallen siege to various demons, beasts, and the undead. You play the role of a hollowed being (with a wide range of class selections from theif to sorcerer) who hasn't yet completely lost their sanity and must fight to keep the small amount of humanity they have left. Your quest takes you through fortresses, dungeons, cities, and forests where you collect souls, weapons, armor, and items that make you more powerful as you progress.
The fun of the game is never knowing what (or who) is lurking around the next corner as you make your way through the world. Nothing about this game is easy and dying is inevitable. So if you've gotten used to all the easy, simplistic, boring games that you can yawn your way through then you can just skip this one. But if you're up for a real challenge that includes epic boss battles and online multiplayer co op and PvP (players can invade the worlds of other players in search of items and also to attack members of opposing clans) then this game is awesome.
