Yeah, if you check (I know it is not 100% accurate) the graph, they are close to $100K for lifetime and $20K yearly, and hell that is pretty good especially if this is just a side gig, as I'm not sure if they do this full-time or not. Most countries especially if it's extra income, $1600 extra a month is substantial.
There are just some games that are going to get crazy and I do mean crazy amount of support, and some just aren't or just be in the middle (like this game), not sure anything could change that at this point in this game's life cycle.
