Genshin Impact

I worry it'll trigger nausea for me.

I think it will end up being something used a bit around but nothing too important. Just like the boat after Inazuma. Some zone here and there, a couple of minigame and all.

It mostly sucks because underwater movement is slow and uninteresting. Jumping and sprinting is a big part of making movement fun, so it'll be interesting to see if they can make underwater like that. That's why flying is also so boring, you don't do anything besides hold forward and lose all forward momentum when you drop which feels super clunky.

It doesn't have to be great, as long as it provides a decent change of pace.

But i hope it will be popular : i'd be glad if they expand underwater exploration to areas like Cider Lake, or between the archipels of Inazuma.
