I don't plan to do anything (no achievements, no cards, nothing). Just have a way for people to play those games on Steam. I also plan to include the Windows version only, since they're the only ones that can still work fine (supporting Mac or Linux wouldn't be worth my time at all).
I'm going to give precedence to the new games of course. This was just something I was thinking to do. Hoping that people don't think those are new games or that they could damage my reputation somehow
