Cool video...I didn't touch a
MS-DOS computer until 1993, but DOS (for me) had been around since 1981, with the Apple II+ my parents bought. The games I played back then are obviously far older than anything listed in your video, so I'm going to go with games I played in the late 80s/early 90s with my first GUI computer, the Apple Mac SE. (the DOS for that being Apple System 5.1). This is what the Mac version of
Might & Magic II looked like back then:


I spent exactly 11 months playing that game (and completed every single quest), and it was awesome. At the time, the Mac had a few exclusive games, like
Shadowgate, and the
arcade-style Dark Castle. Overlapping windows and cd-quality audio/music in games was completely normal for me by 1990, and when I first saw/played MS-DOS games in 1993, it was ugly and alien.
Having said that, Doom 2 and Tie Fighter taught me how to configure himem batch files and sound cards. And they are, to this day, still two of my favourite games.
