>>2I haven't used it very much, but I think it can do anything Java and Flash can do, and more. Not sure though.
And there's a program called Construct 2 that allows you to make HTML5 games without even needing to code, and you can make legitimate games with it.
Of course, you're limited if you use a code-free program like that. But they put a lot of events in the program so you can still do a lot.
People say HTML5 is the future of online games. I agree. I don't think there's anything Java or Flash can do that HTML5 can't.
And with Construct 2, anybody can make basic games. People who can't code can get their ideas out and then people with experience can help the people with good ideas.
So I love HTML5 and Construct 2.
I haven't made any HTML5 games yet, though.
I've been making a Pokemon-like game in Flash for Newgrounds. But it's nowhere near being finished. There's one cutscene and only a tiny bit of gameplay.
I really want to make some sort of medieval RPG. :U
