There was talk of such a thing last year around GDC time but it never happened. Perhaps now that the Game Tech Group is formed something can happen in this area to ignite some spark in the Java Gaming community?
E.g. If publishers aren’t quite ready to take the risks associated with new Java game developers, perhaps some prize money will be enough of a carrot to dangle in front of some would be game developers to produce some showcase works.
If Sun invests some cash in to paving the way, proving that Java enables top quality game development using less resources than traditional C/C++ game developers… well it just might pay off. Maybe a deal to market and sell the winning entry on a popular web site (something that will get more traffic from the target users than java.com)? Of course it will only work if the community comes up with some really slick games and not the “toy” applet games that you see on most web sites.
Things like Wurm, Tribal Trouble, Magicosm, AlienFlux… stuff with some polish. I would like to see something like that get some marketing promotion that actually reaches the gamers out there instead of just us Java nerds :).

? Any?
