why do you even want him to "finish" this game? do you want him to work on something else instead? i honestly don't understand this point. if dc wanted he could "finish" the game by rushing out the updates for the remaining school girls and the dating stuff in a year or so (i'm talking about subpar updates like the first mia ones) but what does anyone gain from that?
everyone who knows just a little bit about this games knows that it's pretty much episodic at this point. you wait for a new update, play through it. wait for the next one. rinse and repeat. it's ever evolving very much like a AAA gaas game in that sense just without the bullshit monetization aspect (in fact you don't even have to pay anything to play it, yet you still complain). as long as dc is motivated to work on this game and his patreons are happy he can work on SS for the next 10 years for all i care. even once all the planned content is finished, do you think people won't jizz into their pants if dc does a poll and asks people if they want another huge eve update? of course they will. there are endless possibilities. what if he wants to expand the map or do some adventure where you go on a school trip with all the girls? what if after finishing all the routes, some additional ones are unlocked that lead into storylines where you can unlock h-scenes with the girls in never thought of combinations like banging eve and rhonda at the same time or jenny and roxxy? what if he does a time skip or something and calls this expansion wintertime saga? i'm hoping i get my point across, most of his patreons (aka the only people he needs to give a shit about) want him to increase the scope of the game like this and give every girl lots of time so every route feels satisfying.
the only point i get would be if DC worked extra slow on purpose or something but i honestly don't see that. you can see for yourself how much he works on the game by looking at his streams in which he draws for multiple hours almost every fucking day. there are also graphs and trackers on the site that show you exactly what the team is working on right now and what's left to be done. tell me one dev on patreon who is more transparent about these things? if you are not satisfied with the speed in which this game is developed you always have the choice of just not donating. your ungrateful ass still gets to play the game once the update is out for free.
