First I bought Fallout: New Vegas via Steam to play on my MacBook, then I got a PS3 so I bought it again for PS3 in order to play it with better graphics and THEN I sold my PS3 for an Xbox 360 and bought it once again for that. I've also bought Dead Money on both PSN and Xbox LIVE... Honest Hearts wasn't out until I bought my 360.
People ask me "Why Nathan, why?" and I simply tell them "Because Fallout is an amazing game." :3
