I just checked the games on ProtonDB. Two games are Platinum are one is silver/gold. Essentially very less tinkering.
Steam Deck compatibility is usually very conservative so even though it says incompatible, it will probably work. Nowadays, I just check if the game has some weird DRM or anticheat, otherwise it just works.
I maybe incorrect but towards the end of the movie, the Emperor asks how Katsumoto died, to which Tom Cruise replies “I’ll tell you how he lived”. So he was alive?
But i remember that Tom Cruise’s character switches sides in the movie after spending time with the Samurai (He was captured by them). He trains under them and becomes a Samurai. In the end, they fight against the (British?) and lose due to a gattling gun. All the Samurai die except for Tom’s character. So symbolically, Tom is the Last Samurai.
