I've recently gotten knee deep into Gacha games (mainly Tower of Fantasy and Honkai Impact).
The former only takes around 20 minutes to do the daily quests on weekdays, but the latter is still giving me free stuff for being a starter for 2 more months and would require greater attention.
The reason I'm saying this story is 'Ending' is because I've decided to just say the 'Universe Reboot' in this happened (the very bad ending). It is a bit different from regularly scrapping a story.
Mostly because the events of this story are canon and WILL affect the reboot. It will even give clarity on how the bad ending came about and can be read without having read this story initially.
I'm planning to make it a Gacha/Otome story where you roll characters that can be romanced in the game, rather than them appearing already. The only thing I'm thinking about is the setting itself.
Whether I should make it a Reverse Isekai in the modern world where Adam never left home, or get him whisked away again.
Other kinks will be figured out later.
