I think for this to work, I need to get involved with those games. W:A iteself (as a game which everyone once in a while label it "a 12-years old dead game") wasn't totally open to or accept TUS from the beginning. Do you think other more-populated games will do otherwise?
Unfortunately I can't find fun in these 3D full graphical games for a long period of time. I believe they give you excitement just for the moment and nothing more. That's why they don't last enough and their companies need to update, update, update them.
However I'm coding TUS2 and it is becoming even more flexible and it can accept new games even more that it can now. But as HHC mentioned, I gotta find a way to earn money from this.
