This is interesting…
Apparently some people at a company called Bytonic Software have put together a new port of Quake II. A couple of years ago, id Software released the game engine to Quake II under the GPL, which meant anyone now had access to the source code to make their own improvements/alterations. What Bytonic did was port Quake II over to Java. :-) This new port, called “Jake 2”, supposedly runs very well and works under Windows, Linux, and Mac OS X. I’ll have to give it a try at some point…
If you want to take a look, check out screenshots, or even download it, you can find it at http://www.bytonic.de/html/jake2.html.
