Java is great.  Java is your friend.  Java is Sun's pride and joy.
Unfortunately, as with all things, evil microsoft wanted in on the act.
So microsoft broke java.  IE has a broken java virtual machine, netscape used to have working java VM, but they don't anymore either.
That was just my little quip about stupid people ruining nice programming languages.   Java was the first programming language I used and it was nice, cause it is based on C :)

These games should work no matter which version of java you have.
