I wouldn’t disagree that Doom is a very good choice here too. The fact that it has become a tradition and challenge to try to run Doom on all kinds of hardware alone proves how influential Doom is. However, I wouldn’t say Dungeon Master has aged more poorly than Doom. Both games are really fun today I think. Dungeon Master is just way more niche, it’s older, it had fewer players and the franchise has died a long time ago, while Doom is going strong. It’s a tough choice and I admit I’m a bit biased here anyway - Dungeon Master was my first true love when it comes to video games.
