Steam Greenlight was actually were I first heard Timeshock! was getting a remake. If it wasn't for Steam I wouldn't even have known about the kickstarter!
Having said that, I'll repeat what I said on Steam: although I'd love to see a Steam version, I still prefer completely DRM-free solutions to Steam where possible. Steam is the best possible way of doing DRM, but it's still DRM. If TSUltra was on gog.com (just like classic TS) I'd buy it there instead of Steam.
OK, no, realistically, I'd buy it on gog.com
and a few times on Steam so I could give away the latter copies to friends, but the point stands.
