I’m always looking for more fat mods for games but finding them is really, really hard. Especially good ones. I think there’s been a thread like this before but I couldn’t find it (maybe I just didn’t dig hard enough, sorry) and it’s always good to start something more recent and see what new things pop up.
There is a wiki, but the page is empty: Mods | Weight Gaming Community Wiki. When it opens up we should all contribute what we know to it. As of me posting this, the wiki is still being set up so we can’t log into it just yet to make edits.
