It’s called Dachon B, and is basically a j3d version of a game I made for work.
Homepage, with a nifty jnlp on the page.
It’s pretty much a normal thruster or gravity type game, except no singleplayer at all.
Some of the cooler thing in there is the collision detecion, the beanshell-enabled console and the sound engine.
I was doing this at the same time I was doing my j3d doom engine, and it was about then I realized j3d was way too slow to make anything “real” in.
In my humble opinion, of course, so you j3d zealots can drop the pitchforks.
