Redundancy? More like meta - it's a game within a game. Because once the squids get tired of real life ink warfare turf wars they'll obviously go ahead and create a digital recreation with all of the conflict and none of the casualties. Because what they game doesn't tell you is that millions of squid- and octokids die each day! MILLIONS!!!
It's art imitating life imitating art imitating life.

Well, reading the Sunken Scrolls, spoiler alert byt he way.

The inklings dug up a fossil holding a WiiU Pad.

They must have recreated it!
