Ok, I'll answer.
You CAN buy the games on a PPV basis. However, they cost $20/each (or maybe $30, I don't remember). There was a class action lawsuit several years back and that's what the courts decided.
So once again, the only people who benefit are the lawyers...
It's not a very widely advertised option (mainly because it's dumb), but it is there if you want it.
Otherwise, you're out of luck.
