If you played the original Splatoon game on Wii U, you would likely know that when you played the online multiplayer matches that the maps used in those matches rotated every 4 hours. Nintendo has apparenetly listened to player feedback and thus in Splatoon 2, the maps will rotate every 2 hours. Of course, some folks will still be upset the game doesn’t just let you freely choose what maps you want to play.
Nintendo hasn’t addressed those concerns yet, but I do think Nintendo does this to keep everyone on the same playing field (quite literally). Instead of splitting the player base, everyone gets to experience the same game. I honestly prefer this approach by Nintendo, but I understand the freedom of choice too. Here’s what Splatoon 2 producer Hisashi Nogami said to edge about the change:
“We feel that part of the gameplay is actually selecting which weapons would be best for that combination of two maps. In Splatoon 2, the maps rotate every two hours, so it’ll be a much faster cycle than the previous game.”
