Holy shit I rarely post and other people are probably gonna pick this apart but lemme take a crack at it.
A. Triple AAA developer vs. small indie team working for free is entirely different, and if they ever release anything ever again be grateful not to sound too rude but they do this willingly for FREE for you. (Also sidenote, GF developed town as an entirely seperate project) it did not affect S&S's development at all. Situation's are not comparable at all.
B. "If starlight is like ya know EXISTS BEFORE MY POKEMON REBORN COME OUT ILL BE MAD AT THE DEV TEAM FOR DOING THING" like what. They're talking about maybe releasing a demo and both games are probably years off at this point. Project starlight and reborn do affect each other but also like eh? It is what it is only one Ame and co can actually make money from compared to the other which is literally labor of love and potential landmine of legal issues.
C. When the heck did anyone from the dev team confirm that "EP.19 the main game is done" that feels like total speculation and pure guesswork but idk maybe I missed thing.
D. There is no problem lol, they release it when they release it.
But seriously when the heck did anyone say Ep.19 was done at any point.
