I'm looking forward to the time when you'll cancel Commercial and I get an upgrade to Pro for 50$

I think this is a good idea, the name "Extra" was bad anyways since you cancelled Standard and the name Extra implies that it's better/more than normal (=Standard), but there was no "normal" (except maybe Lite-C, but that was no "full" Gamestudio). But even without that name issue it's a good idea^^
