Lets be honest, these days if they did put in like FLUDD wep or a map like Ricco Harbour or something most people wouldn't even know what game it was from originally and would just think it was a splatoon thing anyway.
This "OMG KEEP SUNSHINE OUT IT WILL RUIN SPLATOON" is just really silly. The game will survive any themed content whether its gear, weps or maps that are based off sunshine and lets be honest a small little promotion to help keep this game alive cannot hurt. Splatoon already is gettingt crossovers. I think people are trying to keep splatoon "pure" for no real reason.
First people want more content, now its we want more content but on our terms. Dont like certain content dont use it its not hurting you.
This. We see Easter Eggs in ALL Nintendo games. The windows in Ocarina of Time, the masks on the Salesman's bag, damn near all the items in Pikmin 2, the DLC packs in Mario Kart 8, and many more I'm likely forgetting. The thing they all have in common is that they're all VERY well liked since they give nice homages to other series in a way that doesn't detract or feel put of place from the main game. Same can work for Splatoon with weapons, gear, and stages based on other Nintendo games.
