(non-casual) Games aren't generally known for fast load time, sharing resources on a multitasking system, or short playing sessions -- all of which plays to the JVM's strengths (or avoids its weaknesses).

As far as fast load time; just launching my (JVM-based) build tool (sbt) takes 7 seconds on my laptop.

Running 'Hello World' from an uncompressed class file takes 0.12s, and most software is quite a bit larger than a couple lines of bytecode in an single uncompressed class file.

The C version, by comparison, completes in 0.005s.

Yes, recently, Java actually became usable for a lot of seemingly native apps.

And it does this a lot better than the browser.
