Ok. If you want some list I will share my list of games I still go back when I don't have much time to play some new games.
1) One Must Fall 2097
The best robots fighting game - specially tournament mode.
Good graphics, good music, great gameplay.
2) Incredible Machine 2
If you want to think a little bit you can just solve the puzzle.
Again good graphics, nice music, challenging puzzles.
3) 4D Sports Boxing
Nice boxing simulator... Still trying to go for the first place in tournament mode.
Vector graphics with static background. Nice music (specially when MT-32 mode with munt used)
4) Skyroads
I think anyone who experienced DOS era knows it.
Adlib music is one of the DOS best soundtracks IMHO.
5) Lotus 3
Just drive to reach checkpoint in limited time.
with cm32l munt emulation the music is great in it and sometimes I can run it to listen music instead of playing game.
