Ohh come on Herkules - don't be so pessimistic!
I apologize. I'm old, scynic and life has made me hard....
Tech Demos are released every day - they have NO purpose whatsoever, besides showing off some technical features.
Yes, but typically they show what can be done, and not was has been done several years ago...
Sun got the F1 demo made - see how much attention that made, despite numerous (better) F1 games being made.
Attention? Where? Despite the fact that nobody really saw it, there wasn't much to read outside java-gaming.org.
It is all about showing WHAT Java is capable of. What is being showed off today is a couple of tetris and pacman clones - we need far better games to show Java as a viable platform.
Yes, so why show the world that we can do things nobody nolonger cares for bc. they for long are common practise? To that respect a JQuake2 is just a better Tetris-clone.
I say - bring on a JQuake 2 - I'd love to see that - I might even contribute (I am a bit tied down by my two priority projects - lwjgl, and life)
Don't get me wrong - I'd love to see it myself! That WOULD be a proof it can be done at all! But don't expect any recognition in the games development world (or even in the gamers world). Would be an 'aha', no 'wow!'.
This wouldn't create any argument to convert to Java in mainstream games development.
