You know what would probably make fat dosh? Fix up Morrowind. Like, go back, get the game files and engine all together, and fix it up. Hard slog, fuck yes. But it could be done. Fix it all the fuck up, do a big bugfix sweep, but change little else; keep all mods compatible as best one can.
Then re-release for like $15-20 with a big marketing campaign, play nostalgia -gently-, and go hard on the merchandising/after market sales. Release on new consoles.
Cash money + great faith rebuilder.
