Let me put this into perspective then.
Strive for Power was a game that came out a few years ago. The developer felt it was best to put the first game down and start over. The between development of the first game in 2016 and it's sequel Strive: Conquest started in 2019 has been 3 years, and in that time Conquest has made it back to where Power was in terms of development and people are happy with it and it's still continuing along at a respectable pace.
What's LT been up to these last couple years? Well up until about a couple months ago we've just NOW have gotten past what is the beginning section of the game. Since 2017? No way. Poor project management skills aside, it's been a known fact for years that Inno has been combating her own coding since this was the project she decided this was how she was gonna learn to code and it shows. You know what most people dont do with their first creations? Drag its corpse around for everyone to see it's rotting flesh. Most people's first anything winds up in the trash and for good reason. Its a learning experience, its sloppy, poorly made, but it's a start. Just like how writers do second and final drafts, because the first is just meant to get the ball rolling. We're still on the first draft, and if you know anything about first drafts is that you dont keep editing it along the way or else you'll never finish it and make your improvements in the 2nd draft.
This is what 4 years of trying to fix a first draft looks like. I can almost bet you anything that if Inno took a step back and just started fresh, took what she learned from this and made it better, not only would she be back at this point of development within a year's time, she'd likely be BEYOND this. We'd likely not only see FINISHED, FUN, and FUNCTIONING game systems in that time, we'd likely even have the 2nd city be done by that time. Trying to stumble back to work on game systems that should have been done first is what is slowing development down. Nothing is done because Inno doesn't look at one system at a time to finish it, she works on all of it all at the same time and then just does enough to have it just simply exist and then moves on to "come back to it later" which we all know doesn't happen. Starting over I know is the best course of action. I promise you her supporters and detractors would likely be in favor of this.
