I may have the X-box but would prefer it on the PC. You can get mods, when made, on the PC and hopefully something extra will be added like they did with the first game.
No, why would I return the game? It's great so far and have not encountered any bugs. Even if I did encounter bugs I would still keep it. Bugs are the nature of making a game. There is no such thing as perfection when it comes to programming.
