Now I know of some games they've done this with already, but just a general question, if they bring a massively popular PC game to the Xbox, which would it be? (Idea recieved from example: PS3 doing so with DC Universe and CO).
Keep in mind, the question is general and opinionated, simply what would you like to be able to play on the Xbox instead of the computer? (Feel free to explain as you wish).
Remember, this is just a simple question and something to discuss, so have fun with it, and happy gaming!
