Not only are there quite a few, but for me, I prefer third person to first person.superfreestyleer :
I totally agree with you that they're primarily first person. But there are great third person games out there. And quite a few.
There are exceptions, however only one stands out to me.
"Free-to-Play" games are always NEVER free!
Someone once said that if you really want to maximize the profits of your game, you have to make it F2P. And honestly - it's true. That said, there are some free games floating around out there, such as TAGAP.
They will make you pay one way or another, with most of the time you spending more than your typical boxed "Pay-to-Play" game.
