The Dreamcast community never ceases to amaze me. There are loads of intelligent people working up front and behind the scenes doing such things as making new video games or bringing old ones back to life with internet gameplay.
One thing that, as far as I know is never talked about would be possibly recoding Quake 3 to allow more players in one server online. Whether or not this would be possible, is out of my realm of knowledge and would have to be left to someone with a bit more knowledge. It is, however a suggestion I leave sitting here on this forum.
I know, there may technically not be a reason to allow more players, but I think with such a tight community, no doubt we could fill a 6 or 8 person Quake III server.
This would be a less important goal for the Dreamcast community, but maybe someone will find interest and look into it.
