Wouldn't work because every other gamemode is severely less balanced and typically requires admin intervention to play out decently, with the exception of whiskey outpost, but whiskey outpost gets very stale very quickly
I just want the gym. I know a lot of players, including myself, that got seriously disappointed when the gym got implemented in game. First round a bunch of players ran there while staff and devs used OOC chat to shitpost about how "great the gym was", which got hopes up even higher. Serious killjoy for all the people who were genuinely excited for it. A single room that people would go to for goofy workout emotes wouldn't exactly raise the RP standards all on its own but it'd be a nice thing for people to have anyway.
