I don't really mind seeing the other teams' winning animations, but I found it funny how for the first time the losing music doesnt actually sound very sad and you don't see your player character sad either. I dunno if they thought it frustrated players too much lmao
On another note, the nostalgia I have for Octo Expansion is INCREDIBLE. I was supposed to be doing math homework when I saw the nintendo direct that announced it and screamed so loud my dad became concerned (I did the same with the announcement of Splatoon 3). While I don't have nostalgia for that time of my life, playing through and beating octo expansion, reading all the memcakes, listening to the music, was incredibly impactful to me. Changed my brain chemistry I think; now I'm obsessed with metros and light rail. I miss how 8's personality was so visible through the memcakes, how Pearl and Marina's relationship was developed and shown, and how by playing you would get so attached to this little octoling with dreams of the surface.
I definitely think that in many respects, Splatoon 3 is a better game, but I feel like a lot of the characters just weren't shown off so much, so you wouldn't get attached to them. Maybe I'm just not that into Deep Cut, but Pearl and Marina and Eight will probably be my favorite splatoon characters for a long, long time. (hell, I even feel more attached to Four than Neo Agent 3! and Four's campaign was kinda mid, especially compared to Alterna!)
