I really really like this game. It is one of the best erotic games, period. Very few other games on this site come close to its quality.
But questioning the pace of updates is reasonable. Don't get me wrong, I fully understand and respect that quality such as this does take a long time. That's just the reality of it. But the reality of it is that this game is very ambitious and at the current pace it will take an extremely long time to be completed. As I understand this, this next update has taken six months, and the majority of the content is limited to one girl.
The current planned content, at least from what's suggested in game, is huge. At the current pace of the games production, it will take years to complete the content for just the girls already in the game, let alone all content in Old Capital, let alone let alone content for the entire map. I don't think it's unreasonable to suggest at the current pace of production, the game will at least a decade to complete all its planned and suggested content. While the speed will increase as a rhythm is establish and less brand new assets need to be created, unless production is somehow drastically improved or scaled up this game is going to take a very very long time to come anywhere near completion. This is to say nothing of potential burnout either.
I don't mean to be negative, mostly just trying to be realistic. Regardless, the game is extremely good and I wish the devs all the best in their endeavour.
