all i wish to ask regarding the trainer that you guys will be producing -- will it work with both the store bought version as well as the STEAM download version that i have pre-purchased?
Apart from that will sit and wait paitiently playing the free copy of GTA:Vice City i got off steam
1000% impossible to say. Since the game is not out yet everywhere. Once the trainer comes out you'll have to wait and watch the messageboard to see if D2D and Steam people are having trouble.
if it's anything like past LIVE games they will require different trainers than the retail. Hence why i always go retail.
