> Are first generation Java games that far behind?

The first commercial Java game was Tom Clancy's Politika, published in 1997. This was followed by Tom Clancy's Ruthless.com in 1998, and Shadow Watch in 1999. I'm not exactly sure what the comment above means, but personally I consider those games first generation. They were burnt onto CD and sold in stores like many a C or C++ title.

Whereas some C/C++ games have used Java as a scripting language, the approach of these games was to use Java for the core game loop and game logic, and to write new native libraries for the performance heavy stuff like graphics and sound. For Politika, we wrote our own movie and sound code (for both PC and Mac) because Java didn't have very good support at that point. We almost got some faster and leaner 2D graphics support in there too, but ran out of time. This approach was written up for a paper (Writing Java Games: How We Did It), which was presented at CGDC 1998.

In Ruthless.com, the native libraries were improved and the 2D graphics support was added. Basically a wrapper was created around DirectX using JNI. In addition, the whole game was compiled to native code instead of using the Java VM. This whole system hit its peak with Shadow Watch, which is an awesome little turn-based strategy game; think Rainbow Six Tactics.

So this has been possible for many years -- it's just that nobody's carried it on. The big accomplishment here is that they may be using only Sun libraries, which only means that Sun has finally gotten their act together and put out well-optimized code.
