My family would play this as a group. We napped at least the first 12 levels, maybe more. My father loved making maps of old video games. I’m certain that his map of the thieve’s cave in Adventure is still floating around the house somewhere.
You’d probably be able to 100% Turnip Boy Commits Tax Evasion. Only about an hour or two to finish the game, and another 15-30 minutes to figure out the two extra achievements.
No real reason for GOG to take center stage on this one. The reason the GOG version sold so well is that it doesn’t include the latest patch from Bethesda, so FO:L works better on Windows with the GOG distro rather than the Steam distro.
I don’t know if the '93 version of Doom will do it, but it probably will. I installed Dark Forces on a machine several years ago, and was happily playing for about 20-30 minutes when I suddenly got motion sickness. Those older games run at a lower fps, and apparently my eyes really don’t like that.
