So I wonder how long it'll be until it arrives here?

Steam version still needs to get working soundtrack so probably after that.

Maybe after Carmageddon: Reincarnation gets out of Early Access if at all.

On the Steam store page they pretty much outright advertise it as being a terrible game and only put it on there due to many fan requests. I guess you get the game for free when you purchase Reincarnation (along with the first two games) on Steam.

Yeah, I got it free there and tried it briefly, and would have to agree that it's terrible. Carma 1 is still the best of the series, though Reincarnation has recaptured much of the feel of that game with better graphics.
