Any good online co-op games?

Played It Takes Two and really liked it. Luigi mansion 3 is awesome co-op but only local. Just got bro force on sale for 3$ and that is also fun. Play a lot of Splatoon as well and have Mario kart 8. Any other good online co-op games I am missing? I have Stardew valley but never tried its co-op. Thanks. PS. This thread told me to pick up golf story which is also awesome.
