a question about "copyright"

[MystD]

I had an Idea about doing a shop where ppl can play with all the different Consoles and Games for a small fee. Like if they want to test a game or just for fun with many other ppl. I want to know if that is possible, or would I have to pay fees for every game that can be played there. And is it possible to use backups for the the consoles so that the originals don't get damaged. I've heared it is legal to have 1 copy of a game if u have the original. (Germany)

Hope u guys can help me. I'm searching the net since days to get an answer.
