I'm looking for some non-Steam games to put on my FreeBSD installation. Anyone here have any recommendations?

Natively, I play OpenTTD and Minecraft on FreeBSD a lot. In theory, Quake I, II, and III should work on FreeBSD natively, too. There's also a fully functioning DosBox port.

Wine on FreeBSD also works just as well as Linux, and I play a lot of Steam and GOG games on FreeBSD.

I have not had any luck getting Linux games to work through the Linux emulation layer, though. Only a few games' dedicated, headless servers.
