FBT's main use are
>Fullbody avatars in social games (VRChat)
>Streaming 
>kicking women in BnS
There are a couple of lesser games like Climbey that have support, or NaLo (not really worth it, it also uses cheaper alternatives), but let me tell you nothing important for FBT happened since I bought it in 2018, other than BnS. It's a completely retarded purchase when I think about it, I don't even play VRC anymore.
