I'm newbie Indy!
And I want to begin with small Java game.
Problems is that Users had to download JRE (~10M).
What do u think about it?

Some people (http://www.puppygames.net/) are doing it. You don't need the full JRE.

...better clarify that a bit though:

It's not so much size these days, I think, as hassle. 10Mb is getting to be an increasingly small amount of stuff to download with all these wealthy broadband types around, but the hassle of having to install something first is what puts casual players off. It's far easier to find a game that doesn't need a separate installer. If you can figure out a way to do an online auto-JRE install then you're probably on to something. It needs to be addressed. Sun have made some moves in this direction; go and download the Windows online install of the latest JRE1.4.2 - it's only 1.4MB and it grabs the rest online. So there's hope. I might experiment with this.

Also, you can't actually distribute partial JREs; the only way to get around it is to natively compile your application with Jet Professional (http://www.excelsior-usa.com/) which is a little expensive but worth every penny.

Cas :)
