When I was growing up I had a PC that only had DOS 6.0. that was perfect for what I used it for. I still play the games from time to time as well. The game I was playing before I had to move was Raptor: Call of Shadows. This title was made from apogee from years ago, The same guys who made Duke Nukem 1 and 2, Monster Bash, and the first three of the Commander keen games.
Wanna discuss more DOS stuff I'm game for it. I also know how to make DOSBox work with troublesome games like Blood. so if you need me I'll be here.
