I had a dream last night that I was playing Bloodborne, except it wasn't Bloodborne but a first person horror game in a real world type setting. So, in this bit you had to walk through a building full of people, and those people were just standing around but the moment they became aware of you they would turn hostile and come at you (zombies, basically). There are too many to fight through, but you have this mask which you hold up in front of you, and when they see the mask they become frozen, but a couple of seconds after you turn away again they reactivate. So you have to push through this crowd of zombie folk in first person perspective, brandishing your mask, and as you go further in you become more surrounded, it's more difficult to keep all the zombies frozen, and it gets quite scary (because you can't see the ones behind you).
Then I woke up and realised it was the boo mechanic from Mario games (they stop when you look at them and chase you when you face away), transplanted to a proper horror game. And it seemed like good fun.
One on one fighter ditching energy bars and focusing on score attack within the 60/90 sec rounds. Put lots of defence moves in so players can score high with combos or defending a rush down.
Fighters Destiny on N64 was on the ropey side but it had a scoring scheme not far off what you propose there.
You got points for throws and other moves. I think there was a knockout move and a ring out too. There was a grapple mechanic too that might have been based around button mashing but can't remember now.
If you're going to have a score system, you might as well have a use for it. I remember waaaay back when one friend was bragging about his sf2 high score and another lad pointed out that the single digit at the end of the score indicates how many continues he had used. Thought that was quite clever on capcoms part, meant only two zeros at the end of your score was legit
