Good 3D Open Source engines

[sahiphop]

I found one that I think is a keeper guys... again, I'm still learning C++, but while I'm doing so, I'm trying to gather every tool that's necessary to use. I don't want to stick with a Quake or Doom engine... and I realize that I don't know everything that goes into programming a game for Dreamcast (yet) but here's one I found... could one of you guys check it out and tell me if this would work?

It looks pretty darn impressive... I would definitely want to use this if you guys approve... or if you happen to know of any others that would help, that would be awesome. Thanks!

Yes, you can use it. I approve.
But it will never run on dreamcast.

=\ Hm. I'm guessing then the only real engine that will work is the Doom engine then?

The Doom engine is so old… Something based on Quake would be way more profitable.
Something like DreamPlaces, Chui's port of DarkPlaces :
