as most people know, quakeworld is in development for dreamcast. and cross platform play has been confirmed. right now because of the steam summer sale, quake 1 is $1.24 (cheaper than a mountain dew) and it includes quakeworld and the hardware accelerated OpenGL versions of quake 1 and quakeworld
this is a must buy for anyone involved in the dreamcast online scene. if you can't join us on dreamcast because you're traveling or whatever the reason might be, you'll have this on your steam account to join us anyway. must buy for sure
