I agree 100% that modders have made a huge contribution to many games. Isn't it amazing what can be done for love and not money?
I think forming a company of former modders would change things but not better them. Companies tend to want to make money and so on. Why do you think companies like Ubisoft haven't hired all the find modders?
They would then have to pay for what was free before. Modders are paid in love and respect, by us gamers.
