So make them pay up front? Or limit the free trial to a selection of games? Or limit the games to demos of existing games? There are so many options here to limit your exposure.
Those are all valid points, but I think the trade off might not favor them. Although piracy mighttt in some situations help games, I don't see how it could help us. No free trial would mean we miss out on users too. Plus, from what we've been talking with devs, they don't seem to like the idea of being DRM-free.
