Thanks for the reply.
Yes, I've seen this kickstarter, but I wish I saw it earlier.
What about offering a version of a game with less features first ?
But I can understand people want a complete game at the first play.
I truly hope they will remove the DRM, but I haven't seen this very often.. :/
I've been surprised that ubi-soft released drm-free assassin's creed and rayman origins, but I'm still disappointed that games like "hidden in plain sight", "nidhogg", "don't starve together" never lost their DRM, so I'm not very confident about upcoming games.
