Because the game was already getting close to 10 gb with season 1 alone. So if the whole story is gonna be one single folder, it's likely to be 30-40 gb by the time the story is done, which is difficult for people to download and even more difficult for me to upload XD
I'm planning 3 seasons tbh, season 3 will probably not be as long as season 1 and 2 though. Probably... I can't be sure until I start getting close to the end, but probably something like:
12 chapters for season 1
12 chapters for season 2
10 or fewer chapters for season 3
But this is a very rough estimate for not XD
