In the "real" world, 99€ is way too less for the time I had to spend on this
You get everything you need to create every multiplayer game you like. From mmorpg to a cs type game or whatever you like. And this even with the A6 Standard!
Oh, you should also think about how much you pay for native gs multizone support
And 99€ are not much. 2 games for ps3 cost more and with them you can't make money ^^

The price is more than fair!
