as for the arcade game (along with any other DLC) you can go to the xbox website and is a license transfer and will transfer allow you to play with any account. You are only allow 1 transfer per 12months per console/gamertag(i dont remember which).
I had to do it with my Halo DLC when I sent my 360 in for the RROD and they sent me a refurb. They were suppose to do it for me so it wouldn't waste my transfer, but MS screwed up... |
