Good morning. Well bud, all the others (all of them that I know anyway) have monetary sites so I can only guess in their regard to their incentives but I can't answer for any of them honestly. For me I create mods for all the VN's I play anyway for my personal use (that's the only reason I code them tbh, for me). I'm just grabbing a bit of karma by sharing the work I already have. What I don't normally do, which placing any of my mods public forces me, is to update all of them constantly. For the mods I have private I simply update them when I'm ready to play the VN, not caring of when the VN updates. As soon as I make any one of the public that all changes. That's the Achilles heel in the process is that those that are public have to constantly be maintained and thread posts answered. It's more work than I truly want, but I reckon that's the price I pay for my gratuity.
I guess that's it in a nutshell for me personally. I've always tried to be a generous fella and I could certainly use some extra karma considering all the shenanigans we all have had to deal with in the last 2-3 years, right?
Kind regards.
