I need a new game...

Hey all I am looking for something to download and I just cannot wrap my head around anything to buy. I am open to all types of games. I currently have Metal Gear, NBA Jams, Fruit Ninja, and Brisksaber lol... I am wanting something with a story shooter or rpg preferred. I am thinking about picking up Mass Effect or Modern Combat 3. I was looking into that Chaos Online, but not wanting to pay a monthly subscription since I already have a SWTOR account. Any help would be sweet. Thanks all

I have a suggestion. It's no RPG, or shooter. However, it is awesome, addictive and is good to play on the side of a more demanding adventure. http://www.nextsavepoint.net/2012/01/triple-town-trap.html - I wrote a full review here, see if it is for you.
