| TheBraveGallade said: of thouse, both mario kart and smash are complete games without online, and animal crossing's updates are free and don't require online either. only splatoon i'd consider truely online dependant, and doesn't it come with 12 months of online? |
Smash and Mario Kart are very dull without multiplayer, their selling point is competition even if on friendly matches. In the past it used to be local coop, but social relationships changed over the time and nowadays kids and teens are more likely to play online with their friends
For Animal Crossing I can imagine playing without online but would be a far worse experience. It's a social interaction game, look how the franchise popularity exploded after pandemic, people were using this game as a way to socialize
Funny, Splatoon is, among those, the only one who I think could really work as a solo game, even if somewhat smaller
I'm sure it's just a matter of time before Nintendo release a full single player Splatoon spin off. But yeah, online is the bread and butter for this one. And I think those 12 months online were offered only before Nintendo Switch online was released
