At some point the Development team for Girl Life will need to hunker down and start to fill in the many plot holes in this game. There are a lot of roads that lead to nowhere and some of the old stories either gotta be dumped or revised and finished. I'm all for new stuff and all but, I believe it beneficial to have some sought of defined path forward with MC. Being this is my favorite game on f95, I really hope they'll be able to accomplish this.
A few things.
1) Everyone works on the game for free in there spare time. Which means mostly people work on what is fun to work on and working on the same thing tends to burn you out. So moving onto other things and then coming back later works better for more people.
2) If all we do is work on a couple of things it will make some people happy but others unhappy because they might not like that story arc, npc etc. So if we spread stuff out everyone gets a little of something they like.
3) As for as plot holes as you call them and unfinished stuff a lot of that is because people do it for fun. So often you get people to come work on the game then either get bored, RL takes up their time or something else happens and they stop working on the game and many of us left don't know what their plans where and it is very hard to pick up someone else's story in the middle and finish it. We do it, but we don't rush it, we wait until one of us has a good idea on what to do next with the story and then work on adding to it. A example of this is VK's work on Fedor and Niko, due to reasons I won't get into she started work on her own patreon funded game and now she spends almost all of her time on it. She says she still plans to make time to finish their stories, but when is anyone's guess. So we will give her time and if enough time passes though they will eventually get finished by someone else.
4) Nothing is going to be "finished" any time soon, as I have stated before in this forum. The long term goal we have of the core dev's like Kevin and myself and others is. We plan to have 1 year of secondary/high school content, 4 years of uni content, 2-3 years of post higher education content, plus a smattering of less jobs and varies side things worth of content. Or 7-8 years of in game content. We are somewhere in the middle of year 2.
So we have a overall plan but it will be a long time coming before anything is "finished".
