Ah, I remember the days of Quake 2. Running and gunning. Brown environments. The Quake 2 benchmarks for video cards. Oh, those were the days. Now, get your mind around this: The Quake 2 engine has been ported from C to Java. Very cool! Check it out here, the Java Quake 2 engine is named Jake 2. You can even play it straight from the web (be sure you have high speed).
