CtrlAltDelicious, 10 months ago IDK if released as a "cloud edition" or native, but https://www.nintendo.de/Spiele/Nintendo-Switch-Spiele/It-Takes-Two-2265759.html is probably the best co-op game we ever played with my wife. We played streaming from PC, IDK how good Switch port is. Other than that, some of our favourites (tried to sort by relevancy to your question): Children of Morta Overcooked 2 Guns, Gore & Cannoli 2 River City Girls Death Squared (not PvE, puzzle game but a great one) Snipperclips (ditto) Super Mario Bros U Deluxe Luigi's Mansion 3 Pico Park (better with 4 players) Unrailed (maybe not very casual/easy though) Other games that may not be your cup of tea but still: Mario Party games Warioware Get it Together Crawl TMNT: Shredder's Revenge Super One More Jump Out of Space Enter the Gungeon Marvel Ultimate Alliance 3 Urban Flow Catherine Full Body (has a co-op mode)
