Elmofongo: Like even by the standards of 8-Bit games, there's something just boring about 1980s 8-Bit DOS gaming, like I'd argue the NES was the far better gaming device because of the library it had. Like the only DOS games from back then that I feel were worth playing were the CRPGs like Ultima and Wizardry and the SSI Gold Box games and Adventure Games like King's Quest and Leisure Suit Larry and Zork.
The bulk of my 80's gaming was on a ZX Spectrum, though after receiving my first 286 I had a lot of fun with Prince of Persia (1989), Where In The World Is Carmen Sandiego (1985), Where Time Stood Still (1988), Gauntlet, Outrun, and a number of great early point & clicks (Indiana Jones & The Last Crusade, Maniac Mansion, Kings / Police / Space Quests, Zac McKraken, Leisure Suit Larry, The Black Cauldron, etc).
Having said that, the gap between, eg, Dangerous Dave (1988) vs Doom (1993) or Zork vs The 7th Guest was utterly huge and had a 100x greater impact on PC gaming in just a few years than the minor gameplay gap between Deus Ex (2000) vs Deus Ex Mankind Divided (2016) in terms of inventing whole new genres / styles of games with "on another level" jumps in depth of story, gameplay and introducing 3D T&L acceleration vs software rendered games.
