Boys, your complaining about fps and prices sounds funny to me. Did you ever look at the feature list? Did you ever compare those features to other engines? Do you know how long they have been working on this? Did you see the video?

The price is 1500 and a second payment when you launch the game. This is not a 100 $ engine but it also is not build to create another clone of Tetris or PacMan. This one is for serious ambitious projects looking nearly as good as a movie. You need good artworks, a team and can build a game for modern hardware.

And when you are able to manage such a project then of course this price is a bargain. And since you need years to complete such a game it is no problem to pay per title.
