The issues with this game is that you need to not play for a year or two for the chances to have a solid gameplay like you said there is too many pathways and the dev deliver one update per month I think a update every two months would probably be better
Nah it has nothing to do with that. Any true alien get anything after you "wait for a year or two"? What "Gameplay" you even talk about?
The problem is the dev don't have a comprehensive creative vision, do not set limits of what's "achievable" in terms of game-making.
Instead just do whatever they feel like atm / currently popular or make them money. This is also one big contributor to scope creep.
On top of abandoned game branches, the new MPreg they want to add is also a good example:
Instead of doing scripted MPreg events for selected characters
which are actually achievable,
they want to do a whole sandbox system where everyone can impregnate everyone (like TiTs), which requires a whole rewrite of codes, complex encounters & interactions, etc. Even worse if they just use procedural / AI generation to fill in the writing, it'll just be boring and meaningless.
