Cant Launch if not in Applications folder

I am giving this 2 starts because I cant put the game into my Games folder. After asking for my admin credentials it will move the app, but you cannot launch the app. A message pops up saying it is damaged and needs to be downloaded again. If I copy the game back to the Applications folder it works. Why do I have to have it in the Applications folder? I dont want 1000 apps in one folder.
