Ghost of Tsushima + Red Dead Redemption 2. I basically want a samurai game very similar to Ghost, but made in Rockstar's engine, with Rockstar's attention to detail, world building and realism, with fluid Ghost swordplay, the Ghost levelling up mechanics (but a but more grounded), all different armour sets etc, but realistic dismemberment, etc.. Also, time wise, I'd set it forward in time a bit compared to Ghost, make the backdrop the end of the Edo period, you play as a Shinsengumi and make the map fucking gigantic and include all of Kyoto and its outskirts and surrounding countryside/towns.
