The title basically says it all. Though I do know that Sonic CD for Sega CD and Sonic R for Sega Saturn have been rereleased as part of the Sonic Gems collection, but have any other games for the short-lived Sega CD, Sega 32X, Sega Saturn, and Sega Dreamcast system ever been rereleased for any other video game systems? I'm mainly referring to rereleases as part of a video game collection release, but stand-alone releases are also okay. I'm pretty sure there haven't been "collection" releases themed around those system like there has been for Sega Genesis.... But I think those would be interesting ideas. Gamers who want to see what the games for those systems are like wouldn't have to track down the actual systems.
