Well that escalated quickly. English isnt my first language, so i hope it's not because of that. But my post was a reaction to a post above..
First, i didn't wrote 'most updated game', i wrote 'updated regularly'.
Most games are a bit prėworked at the beginning. Before you put it out, most work one or to updates ahead with a bit less content. Start small and then let it grow. So future updates were you can't work ahead take longer. While a lot of games are abandoned after a couple of updates, and yes, some take ages to update ( like that femdom game that isnt even on hold for a year because of their monthly wallpaper post) i find that Hillside is updated regurlalry yes. And 3 or 4 updates a year for these kinds of games/vn's with almost no templates take time to produce.
See games as GGGB or his new game, or that Anna game..regular updates at first, after the first update as the story gets further and more complicated as when they started on the game, updates take longer.
