That's great to hear and everything since ME3 is in my short list for best game of 2012. It's an amazing game and a must play. The problem is that it's already available on the competition and by the time the Wii U game releases, it will be really old and much cheaper, too. On top of that, it's the ending of a trilogy where the actions of the earlier game has bearing on the final game. Even if it fixes every single glitch and complaint I had with the 360 version, it won't mean a thing because that guy I met in ME1 won't remember me in ME3.
ME3 is one of the best games of this gen but I don't suggest that anybody start the trilogy with anything less than Mass Effect 1 on the 360 or PC.
