I remember we tried that with the devs. They weren't having any of it. "We ARE Ubi," they said. "Without Ubi there would be no devs" they said. I hear a faint echo of that now, growing in volume as their numbers grow.
This is not a chicken or the egg riddle. Clearly there must be a game before the modders have anything at all to do. Clearly modders can only do what the design of the game permits them to do.
I admire the modders greatly, but they admire the game and the people who made it. Who am I to argue with superior reasoning?
