A single-player fantasy game with no skill points/upgrades beyond equipment. I want the entirety of the progression to be the skills of the player. You end up losing fights to more than one goblin at a time, but then you learn to start dealing with groups. A long enough time pasts and you’re slaughtering hordes of enemy like clockwork. But if someone took control of your character they’d still lose to a goblin or two.
I want something where split second reaction times and skill determine how a fight goes. Both me and the enemy should be able to kill each other in 2-3 seconds given the right circumstances. I want extremely punishing mechanics for both enemies and the player. Something like a first-person Hotline Miami but with really good swordplay.
