Do you know what's the real problem?
People want to do some clicks and see a result - a commercial styled game.
But this is far far away from reality. Gamestudio offers everything (except a good Level Editor) what you need for developing a game.
There are good Java libaries for developing mobile games - libgdx for example. I wouldn't miss this feature.
Debugging is a mess but I am still comfortable with Gamestudio. I need just a new WED or a patched GED.
