When I was a kid, my friends and me all bought the Groudon edition of the game (Pokemon Ruby), in secret, so the other kids wouldn’t ask to borrow the game or play until we were done with it.
So then none of us could have the guy from the Sapphire version. The slightly richer than me kids then got Emerald version and idk why (I had Rayquaza in Ruby so it wasn’t needed).
In short, we never got the other pokemon or the exclusive ones (there was a couple of them besides the legendaries).
Let it be a lesson xD
