>Lets go to the beach anon
Not actual "summer" games, but these games have some fun beach levels.
Super Mario Odyssey had a fun beach level, complete with a volleyball minigame you played to earn
BOTW had some nice beach areas to the south, though there's no diving and the sailing is very limited. Didn't even get a gust jar or a wind waker to change the wind so you could herd a fucking forest fire through a moblin camp.
Speaking of, Wind Waker is pretty much all ocean so I guess by default it's a beach game.
There's also the Senran Kagura water pistol shooter, though I never played it. I assumed it was a B game at best that sells on T&A.
And Kadokawa Jet Girls seems like a summer game but I heard mixed opinions on that when it released.
>Hold the fuck up, Tekken had a volleyball mode?
Tekken 3 had a volleyball mode you could unlock. It was a fun novelty but it got boring fast.
