There is a sale on steam right now and I'd like to buy a copy of Warband for my fiance so we can play cRPG together but I've heard that having more than one key at the same IP can get you banned. I seriously doubt she will ever want to play Strategus or use the marketplace and if that is the only concern I will make sure she never does. I have never used the market place myself and don't plan to anytime soon if ever. Are there any exceptions to the 1 key per IP rule? If only one of them plays Strat and neither of them use the marketplace, I don't see much room for exploiting, but I really don't know.
Please help me figure this out as the sale ends tomorrow!
