Ubisoft showed off a casual-ish title during its press conference, The Mighty Quest for Epic Loot. The concept is simple: get and keep stuff. Sounds like a simple premise, but in reality the process is not exactly that.
First, pillage castles. Make it successfully to the center of a castle full of traps and enemies and plunder the loot room. If you don't succeed, however, the castle owner wins and gets loot instead. Now, how you succeed in a castle is up to you. There are 3 character classes that allow you to fight up close and personal (The Knight), from across the room (The Archer) or a combination of the both (The Mage).
Second, defend your loot. Build castles with devilish traps and tons of enemies to protect your own loot stash in the center. Once complete, the castle will be available to others to enter and try and make it out with YOUR stuff just like you have done to their stuff. From the site, "Remember, a house is not a home until it can kill intruders in at least 7 different ways simultaneously!" Sounds like a challenge to me.
The game is, of course, a free-to-play setup with premium items available for real money. Since the game is currently in closed beta, the easiest way to get in is to make an initial purchase that will get you in immediately. If you don't want to pay any money to get into a beta program, you may also sign-up and wait to be chosen. Neither choice will hurt their feelings.
I am currently awaiting my beta key anxiously. This type of game is right up my alley.
