Hi!
I think Patreon never will be fully popular. In Eu, I have to pay 6,35$ for the $5 tier because of the taxes. It's 27% here.
Anyway I like the new % bonus koban system however the patreon site is still a negative trade for us.
Only the tiers with the bonus girls have considerable value.
In my opinion if you really want to be "big", do in-game vip levels, limited in-game offers, new level offers, where we can support you directly and where everyone pays the same.
