I'm looking for some fun DOS games to play in DOSbox. For the past year or so, I've been hooked on Nethack, but I wouldn't mind broadening my horizons. Here are some requirements:
- A really high replay value and/or a lot of random generation
- Little to no mouse cursor use, using a cursor in DOSbox is really screwed up for me

I personally enjoy roguelikes and shoot 'em ups (i.e Touhou), but I'll take other suggestions too. Thank you.
