Pokemon timeline is linear as fuck. We dont have constant and variables, we have pretty much linear as fuck plot, no choices. Capturing legendaries is considered as non canon, since you can recapture them in other games too, but that's not important.

Ruby&Sapphire were first and last games to introduce a kinda different plot based on the version you bought. That was a mistake, because as I said, Pokemon timeline is linear and that shit doesnt make any sense.

Then Emerald came, fixed shit out of it, made a nice clash of gods kinda thing, introduced and provided Rayquaza a role etc. Everyone was happy, because that made sense and was awesome.

Now, after 12 years we got the same shit again. You would call this something like a huge step backward, but nah.

Yeah, an asspull to excuse clusterfuck of the universe we have now, right? What makes Archie winning over Maxie and vice versa? There were no constant and variables introduced.
