I do agree that, because the objectives and overall context of the cellular stages are different than those of the late multicellular, there should be different implementations based on which stage the player is on.
Speaking on the discussion/example given by «Lan», I want to mention that, if the devs were to implement «mechanics that change how the player experiences the world, based on their organism’s senses», then I think this is like sort of the ‘minimum viable implementation’ (if that makes sense).
It’s obviously important to discuss multiple implementations (even the ‘minimum’ or ‘basic’ ones), and because of that, I think one could elaborate more on this idea. I think view range can definitely be implemented for some or all senses, but I think there is more that can be done with this idea than just view range/fog.
I wanna point towards the thread that «the confused protist» mentioned, and say that you should definitely discuss your ideas about the cellular stage there, because in that thread, you can build on previous discussion. I’m also mentioning this, because I think I’ll also try to experiment around with some concepts in the current game using «reshade» ― if I can get it working in thrive. Getting some discussion revived there could be good, is what I’m saying. I just love the concept of stylising how the player sees the world/game.
