"Nur eine Frage: Könnte Map-Edit teoretisch Wed total ersetzen? Das würde Gamestudio sicher ganz weit nach oben helfen!"

Game.Edit COULD replace WED if you build up your level out of entities. Block Creation with GameEdit isn't planed so far (tough it would be a nice feature of course)

"when is it published, how mush is it, where can i download it? "

1) the conitec version will be published in the next 1-2 months.
2) The GameEdit Version by me will be published around 2 months later.
3) There's no price until now.
4) You'll be able to download it after you bought it
