[Kerbal Space Program] I bought the game on the KSP Store, but I want it on Steam. Will you give me a Steam Key?

The option to transfer Private Division Store licenses to Steam is only available for those who bought KSP before it originally came out on Steam, March 20, 2013. Note that if you do qualify for a transfer and choose to do it, the process is OPTIONAL and IRREVERSIBLE. 

If you are eligible and wish to transfer your license to Steam, please submit a support ticket here.
