I'm quite baffled that they didn't announce Paper Mario before this. Only 2 months prior to release? We've seen footage of Breath of the Wild 2 and it could still be years before it happens... Not to mention heavily advertised games like No More Heroes 3 that still don't have release dates. Such a weird strategy...
Following Rie's comments on the Octo Expension, I got it and played it through... and I can't say I'm convinced Octoling has even been considered. There's a drastic lack of personality to that one. The DLC is mostly a collection of random levels, much like the secret areas in most Super Mario games like in Sunshine: just patched together to make interesting obstacle courses, but with little story behind them. The protagonist is silent, and there's no new mechanic. They do look goo, and they easily could have been skins/echoes to Inkling (I'm surprised they didn't make 2 female and 2 male Inklings Octolings instead to promote Splatoon 2 a bit more since it's just aesthetics), It's a great IP, and I like the playstyle, but Octolings definitely didn't make a strong impression, and they feel like characters you need to have played a single specific game in details to even know of them, with people otherwise assuming they're the same as Inklings... Too bad, I was starting to buy into Rie's gospel
