Well they said there will be no paid DLC for Frontiers so that is probably a tease for a sequel of Frontiers otherwise there's no reason to show something like that.Decided to go for 100% map and challenge completion and clean up any of the side stuff with Amy/Tails/Knuckles.
So there's these things called Egg Memos that you can get from fishing, and they seem to fill in Eggman's side of the story. Has some neat tidbits in it, I can't remember the last time South and West Side Island were explicitly named in series. (Sonic the Fighters for the former, I think?)
Only thing of note is that
Eggman manages to preserve a bit of Sage
If you have beaten the game, can you answer:
1. Is there a fifth cyberspace theme even for maybe the final cyberspace stage or just one stage in the fifth island or something?
2. What themes are the other two islands if the first three are: grass, desert and volcano? Is there snow island, ice island, water island, futuristic island, etc?
