I don't see how being able to give away games would be bad for business. I do see how trading could hurt business, but that's a narrow view of things. It might be that the ability to trade attracts more sales than the trading itself costs. I don't know if that is actually the case, but I wouldn't be too hasty to dismiss it, either. The same goes for renting. Granting people the ability to try out a game before buying it could increase sales. Many of the games I play I don't even come close to finishing. If there were a cheaper (and easier) option to try out a game for an hour than buying the full game in a physical store and then hoping I can trade it off later on, I might very well be interested. I never quite understood why shareware games went out of favour.
