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.

I have this concept for a VR team battle game where you have to learn to actually cast spells through complex real time action. Like a mix of moving your hands in patterns and adding elements via hot bar in sequence and saying words via headphone. 1 on 1 or team vs team strategy game where complexity makes stronger team spells and counters. You could have casters who specialize in defense, offense, healers, traps and counters and how you build your team makes for strengths and weaknesses.
