I don't think its a good idea to ban ghost shooter clones because ghost shooter is a demo not a game
Emphasis mine. The key thing here is Ghost Shooter is not a finished creation, so I don't think reskinning it and posting it here is what this forum is for - it should be for posting finished original creations. If someone extended the Ghost Shooter game with powerups, several levels, new enemies, a menu and a high score, that's fine, it's a finished game. The tutorial makes half an engine for the purposes of teaching people how to use Construct.
The correct thing for GS modders to do, I think, is to post the .cap file to the Uploads forum, and ask for assistance/comments on their expansions. Since only beginners will be modding Ghost Shooter for educational purposes, if everyone can look through their .cap, they can comment on events they've added, easier ways to do things they've tried to do, possible problems etc. and then they can learn more. They shouldn't post EXEs to Your Creations, though, because they won't learn anything.
In short, with Ghost Shooter mods, don't post EXEs to Your Creations, post .caps to Uploads. That's my stance, anyone with me?
