I remember Mansion of Hidden Souls being described as Sega's version of The 7th Guest, which is one of the two games (along with Myst) that launched CD-ROMs as a viable storage media. My parents were playing The 7th Guest when these games came out.
Warsong was a US version of Langrisser. I have the Langrisser I & II compilation released by NISA on Switch. It has an option to switch between thw original Genesis artwork and a more modern style.
I remember the Night Trap controversy. I never played the game. I also remember that it starred Dana Plato, the actress from Diff'rent Strokes. I think it's on modern consoles now.
As far as games on a Genesis Mini 3, which hopefully wouldn't look like the cheap Genesis 3 units made by Majesco,I think all the really good Genesis games are on consoles now. The only games I am really interested in are Lunar 1 and 2, Vay, and Popful Mail. All of these were Working Designs localizations, which apparently means that the rights to these games are pretty messy. That's a pity, too. Lunar 1 and 2 were awesome. Not only were they the best Sega had to offer in RPGs, but they were as good as Square's SNES games. Popful Mail was made by Falcom. Other than that, I guess I wouldn't mind seeing the Genesis versions of the Mortal Kombat games. They weren't great, and the second and third games were better on SNES (the first game was a complete disaster on SNES beyond the censorship), but the first game actually had a catchu soundtrack that took advantage of the Yamaha FM Synthesizer the Genesis has on board.
