I'm four years late to the secret base party, but I got a crazy good deal on an Alpha Sapphire game on Black Friday, so I've been playing.

Pokemon Sapphire was my favorite game growing up. I played through it so many times, had nearly all the secret items memorized, knew all the Pokemon you could find in each of the different routes, and had even memorized Braille for several years to get to the Regis. When I got Emerald, I had a strategy for Sapphire where I would pick up all the items, complete the game in a handful of hours, and feed everything into Emerald.

These games were the best, and it's such a blast to the past.
If anybody is still playing ORAS, four years after it's cool, find me, friend me, shoot me your secret base QR codes.
