By way of StreetPass
When Pokemon Alpha Sapphire and Omega Ruby arrive on the 3DS as remakes of Sapphire and Ruby from the GBA era, they'll be bringing along the contemporary refreshments we take for granted today -- like online play.
But it'll also arrive with a revamped returning feature -- Secret Base. It's basically a personal room for your Pokemon trainer that lets you create your own gym, set up traps for people who wander in, or create a custom decorative area. You can visit each other's creations by way of StreetPass or QR codes, which unlock new decorations or mechanics like faster egg hatching.
Yep, sounds amazing with the enhancements.
