I know that I've got Bastion and Limbo as DRM-free downloads through Humble Bundle. I don't have FTL, but they sell it (likewise DRM-free). Does FTL have some kind of online component, or something? Any reason that it couldn't keep working in the future? I get the point, though. I've got dozens and dozens of games from the 90s and 2000s, and the earlier ones are much less likely to have a reliance on some external authentication server, or something.
