I hope you enjoy it - Mass Effect can be very challenging, but the world is so rich and just so damned interesting that I'm sure you'll love it. All the planets you can visit ... but that rover can be either the most fun thing you'll ever drive or the bane of your existence. Depending on what's going on around you at the time.
And I didn't get my copy of Ghost Busters at either Gamestop or Best Buy, unfortunately. I'll do some Googling to see about a PS3 code.
