what I think I want in D&D

the gods are physical beings, existing within the world and can be talked to and/or killed

there is no turning undead

spellcasting doesn't even use levels or slots, spells just work or require an expenditure of HP or ability score loss (draining STR or CON) or something that replenishes with rest

spellcasting is something anyone can do if they have the right stats

there are no classes

only humans

static DCs for d20 rolls

equipment and gear more important than stats

exploration is more important than fighting

combat as war

leveling up is an explicitly magical THING that you have done to yourself, it doesn't happen often but could be something characters work towards

lore is baked into the world, if the Magic Missile spell exists then people know who created it, where it's been used, and how they might find it

I have no idea if any of this is doable, but I'm going to try
