The announcement of the original games being delisted has even thrust doubt onto the future of S3AIR, which is currently the best way to play 3&K on PC. Currently it requires a Steam copy of 3&K, which is pretty cheap. Once 3&K is off Steam, there's not really any other storefronts offering the game in any accessible manner, so there won't be an accessible way of legally installing S3AIR anymore. The best option being considered right now is to find a way to use Origins instead of the S3K rom, but that does come with a significant price bump that would make AIR much less accessible.
