Ok, I guess that would work.
But I think he wants to able to attach tons of things on the fly with all possible combinations. Lets say we have a game with a knife, a pistol, grenades, and an M4 with attachable silencer, scope, and grenade launcher...
For that you'd need 1 for silencer, 1 for scope, 1 for grenade launcer, 1 for silencer and scope, 1 for scope and grenade launcher, 1 for silencer and grenade launcher, 1 for none of them, and 1 for all of them.
With grenades, a pistol and a knife FPSC can't handle that.
1 attachment is possible, but 3 is impossible. And wouldn't there be some kind of attachment UI?
So many possiblities...
