>>11825454 (OP)woah, a lot of good questions! ok lets break it down
>Wouldn't it make more sense in RPGs if magic depleted HP?It would make less sense, as hp represents your physical health. getting your liver ruptured from casting a fireball, yeah now that makes no sense, haha.
>Using a powerful spell should make the caster feel weaker.And it does, on a spiritual level, so to speak. if HP represents your physical health, a "fatigue" bar represents your physically tired you are, MP represents how "spiritually" tired you are, heh!
>That MP is separate from HP makes no sense.I appreciate the opinion, but as we all know very well, without any real argument, it's just you know, a fart in the wind so to speak, lol
>It would be fun to have a game where you have to balance your magic against your health and weigh which is the better option rather than just going whole hog on MP and popping an ether.sure.
so anyway, I hope it helps a bit!
Could "fatigue" replace mana? it could, if we go for more down to earth, low fantasy for example.
could hp actually replace mana? well sure, in certain circumstances, blood magic? dark magic? vampirism? plenty of options to make lore friendly hp draining spells, hehe.
anyway, have a good day!
