The former is a real problem too. If your game is likely to just stop working sometime in the not-too-distant future, that drastically decreases its value to me. A game that I would have paid $60 for suddenly becomes at questionable deal at that price point, because you're essentially renting it to me. I would never pay the full price of a game for a rental. A lot of the people I know like to enjoy games for a long time, so if you take that guarantee away, suddenly I'm getting a lot less out of my purchase. TL;DR: If you're willing to charge in the single-digits for your game, sure, make it as limited as you want. If you want to charge like a real game, don't try to shortchange me with brittle DRM.
