So I really wanted to try something I haven't done before with pokemon, which is to strictly limit myself in terms of what my main team is quasi-nuzlocke style. However, I realized I would have to delete my current saved game or download a 3rd party program to backup my original save, PLUS I fucking hated the story for sun/moon, and remembering that I'd have to go through all of that again turned me off to the idea.

Is there another game even remotely similar to pokemon out there that largely captures the same feel?
