Yes it is lol. You know those campaigns are under 4 hours combined right for any decent player? And theres like no online gamemodes
Tbh ask people what they would prefer an octaling or Geno, Isabelle or Issac and the choice is pretty clear.
In terms of online and singleplayer game modes, there are 10 total in Splatoon, with one of them being DLC.
And yeah, you can get through Octo Expansion pretty quick. Just like how you can beat Mario Odyssey in about 5 hours if you ignore everything, and how you can run to Ganon whenever you want in BotW. Longer playtime does not always equal better experiences. A Hat in Time can be beaten in about 3 to four hours, and it's held in the same regard as games like Mario 64.
TBH though, I have a feeling this is nothing but bait, so I'm just gonna go ahead and assume most of your replies will probably just be "LOL Sploon sucks". I'm sorry if you feel that way, but there is nothing that I can do to change that nor am I trying to. And I'm
definitely not gonna try and speak for an entire community and say what they do and do not want. Let's just agree to disagree and move on, as any further discussion on this will most likely be pointless.
