What I really dislike is the fact that the 200€ basic thing has no C++ support. Seriously? Thats really nothing good at all, the price of the pro version isn't that high compared to the fact that you get the full source code and can hack around in the engine kernel to fit the engine more and better to your game (thats something Unity and GameStudio are missing).
Anyway, while you are discussing the final prices, please consider making the C++ interface public to all versions, this will surely generate you much more users!

And not only this, the version with C++ interface isn't available on the engine launch. Not a good decision imo.
