Alright, we gotta figure out how to get this game more ridiculous, and that ain't gonna happen without us all learning to mod this shit more so.
We've gotten custom kits (uniforms) working as well as custom numbering and lettering on them. I know some /pone/ guy got their teams faces replaced with pictures, but I know we can do better than that if we put our minds to it.
I plan on spending part of the week going through what I can of the tutorials on implyingrigged's wiki, as well as just going through the files themselves to see what we can change. I think the priority should be things such as pitches, player skins/models, and little fun shit like menu items.
I got a few things I'm looking into already, but any help would be appreciated.
Here's a good place to start:
