I played Heretic last year for the first time and it was great. So only 25 years late to the party.
I probably will try Master of Magic when I have time later this year. That is also from 1994 like Heretic.
Less incredible jumps: I played Doom64 for the first time with the Switch release. And my first outing to Ocarina of Time and Majoras Mask are the 3DS remakes. I played the original Resident Evil first on the Wii. All of them great games.
