I used to play tons on Doom over serial cable with one of my friends, and when we went around looking for other games we could set up Wacky Wheels was one of them. I don't remember how we found it, or even that it was very good, but it was a lot of fun.

DOSbox is pretty easy to run btw--you don't need any special hardware or a dedicated environment like a virtual machine or anything. Just mount the C: drive by pointing it to your games folder and you're good to go.
