Nice that you mentioned the addictive qualities of FlyingGuns.... :-/
In all seriousness...make the **** thing 100% webstart, not 50% webstart! I swear you'll get many more players. We know j3d is a dead and miserable tech, so how many of us want to install the darned thing? Don't give us the choice...just do it behind our backs
(if the stumbling block is Sun not having a webstart-extension JAR for j3d, then put one together and JGF can host it - I'll then get all the other j3d games using that same JAR, and you'll all benefit from reduced download times).
