Ok. Basically, where im from, you can use an old steam account for every new game u buy. As i am Vac Banned, i can play source engine games still, as Vac bans by engine, so if youre vac banned, it doesnt affect every game. What im not sure about is, you can buy Cod4 and Cod5 retail, and steam isn't needed. Im wondering whether this is different for BlackOps, as it's apparently using Vac.
