>>38820121probably be my own shitty redo of Red and Blue full of DEEPEST LORES (I think the only mercy you'd get is that the 'deepest lores' would largely be optional stuff you'd read on computers, in books, and if you told Lance 'hey, fuck you, I WANT to get involved')
Probably would want sprites of basically all pokemon up through Gen 8 (not even sure you'd get a chance to encounter gen 8 mons though)
But some small details would include the chance to fight a young Kukui, meeting other future characters or seeing reference to them (like Giovanni's computer referencing some events to ORAS*)
You'd also get a chance to capture later gen mons and travel to Johto where an 'original story, do not steal' would await you.
I'll share more if anyone's actually interested but I think everyone's suffered enough cancer from that autism.
*if I recall the timeline of the games right, ORAS/Ruby and Sapphire actually happen concurrently to the events of Red and Blue or maybe only six months after. I was shocked to find out myself.
