Well, looks like the both of us had the exact same idea, as all of the above applies to the vertical games also. They have the server and one does pay a fee. Everyone has their own banners, gets access to email and other info on their own players (you decide what they input to register), and has access to backend for their own instance. Each instance of the game is totally seperate and nobody can access anyone else’s backend.
Installing it is also just some code. One can customize one’s room.
So, I guess we have the exact same idea.
I wonder what criteria would make one better than the other? I suppose cost, ease of controls (vertical is easy enough for a tech idiot like me) and the feel of the room. And/or?
