LOL, games with active hard core players doing Ironman challenges...
Okay Any of the Civ games, Xcom games, I know a lot of people did it in early CRPGs like the Gold Box series, Neverwinter Nights and so on. In today games I have seen people doing it in Cyberpunk, modern CRPGs like Solasta and the various Pathfinder.
Ironman gaming has been around a LONG time.
