Lord of the depths
I really would enjoy a gritty pseudo dark age game. I think it would be fun and I like the aesthetic.I am so tired of "quirky and unique" being the top priority for some very many players.
As you point out though, many players want options. No options generally mean no players.
I feel for you! Though I will say I have found fun in adding some new things and when others do so, it often does not detract from my fun as much as I once assumed.
Half orc paladins! Heresy! Later I played one. A dwarf wizard! No way! Later I played one in 3e…
But as to special…I always play something that is special and unique. I think making up unique things is the fun of characters for most of us. I don’t want to play Bob the fighter…but I never disrupt things of f with the DM either. I hope you at least find some folks that can strike a balance and meet you in the middle!
