Today, the Kickstarter-funded project "Shadowrun Returns" announced... a modification of sorts to their original project. You see, they had originally promised DRM-free copies of their project as part of their Kickstarter rewards. The key phrase is "DRM-free": Many modern PC game stores - yes, including Steam, this is why people used to HATE Steam - have technologies that allow the owners of those game stores to remotely disable copies of games arbitrarily.
