You have to beat the game first to unlock it but I love the realism mode in jedi survivor. Lightsabers actually kill like in the movies, but get shot maybe 2x and you're dead.
This is how harder difficulties should be. You have lower HP, but so does the enemy, forcing both parties to think things through before running in guns a'blazing. If you have to make enemies bullet sponges in order to increase the difficulty, then your AI programming is bad and you should feel bad.
Modern fallout games do difficulty badly. Walked up to one of those boomer guys in fo:NV , he gave me some shit, so I shot him in the face with a revolver. He didn't fall over dead.
I got a bunch of mods to make everyone a lot more of a glass cannon, but made power armor very effective (and other armor somewhat so). Was a lot more fun. But also there was a lot more reloading because, like, sometimes a baddie would get the drop on me and I'd be dead from two shots.
try fo4 survival mode. you can actually die from a bloatfly swarm if you arent careful, but can also eliminate an entire raider base with 1 well place molotov cocktail
