grunthos64: Actually in the fine print of the EULA they are called 'licenses' not purchases. All that really means is if anyone is caught pirating out their game copies, Gog and the other publishers can cut you off and demand you delete your games.
I probably should have phrased that better, my apologies. I know that with all games, all we are ever purchasing is a license to run it (unless you are on Steam, then it is a subscription). However, GOG games are treated more like purchases than elsewhere. You buy it, back it up, and it is yours to keep unless yes, you do something illegal enough to have a company show up at your door and revoke it.
I guess that is what I was trying to get at. Sure it is a license, but it is still treated more like a purchase. It is the user's responsibility to care for it in the end, and other than delivering the game to us in full, I cannot imagine GOG being bound by any other obligations should they run into trouble and shut down (which I pray they never do).
Although, I would hope they at least would give an early warning. Considering they updated the community on games that had to be removed from the service in the past, I imagine they would do the same in this scenario.
