/vt/ - Virtual Youtubers

So I'm considering trying to start something of an "Arena" styled function for content, where it'd basically be built for participants of all sorts to drop in (VTubers welcome to participate, but not necessary), try to win what they can, and I want to also just have things like a little trophy room/hall of fame I could update over time and put names for people who win lots of matches or specific challenges and let it grow over time. The games I'd choose for it would regularly change (Maybe have like, two weeks sectioned off for one game, have people play as much as they want, and have weekly exhibitions/tournaments before moving to the next one), and I could try to seek perms where it would matter. Other than the most obvious problems:
>Initial playerbase would be low, and I would need to find a way to entice people to join in
>Contracts that might hamstring me with certain VTubers
>Pointlessly high effort for just streaming mostly regular content
what would be the other potential problems with doing this? I feel like I /could/ do it, but I also feel like the absence of anybody else doing this is a silent warning of something I haven't been able to predict.
