Looking to play a Centaur in just about anything

Hey guys, I'm a long time D&D player, dabbler of other RPGs, tabletop game fan and have some experience with Roll20 One thing I haven't been able to play, even if the rules existed for it (like in Shadowrun) is a centaur.  I love centaurs. Fav mythical creature (aside from dragons) However, I'm having a hard time finding a DM/GM that will even reluctantly agree to let me play it (even if it's in the core rules. I'm not talking homebrew).  I don't want special stats or extra moves. I want to do it to role-play my fav mythical creature and to create a character that isn't the same boring human, dwarf, or elf combo that's in every single RPG.  So instead of trying to bug every game out there, I decided to post this here and see if I could find somebody (anybody) who would be willing to let me play a character like this.  I'm housebound, so my availability is almost always open. I have dr appointments and a (sadly) steady sleep time (10pm), but other than that, I'm golden.  I'm not a min/max player usually. I just want to have a purpose in the team and a character i'm happy with. I love storylines.  Again, ANY game is awesome. I will learn any system, i'm a quick learner and love getting to know new world settings. 

I'm willing to work with a GM to get this to happen in a fair way, also. I can be pony proportioned (but still ranked as medium or large) so the centaur can believably fit in places like taverns, etc, I'll take a dex penalty to stair climbing, I don't want strength or speed bonuses, i'll take an AC/agility/dodge penalty for my size, I'll deal with NPCs treating me unfairly or with NPCs not noticing me. I'll take a stealth penalty. I'll take more expensive armor cost because things aren't built for my kind.  I'm not trying to play one to hog the spotlight of the game, though I do love it when DM/GMs use hooks to pull characters into the campaign. 

Something to keep an eye out for is if someone runs a Mazes and Minotaur game again (The GM disappeared suddenly without warning in the game I was involved in).  It's an interesting system and has centaurs as a core starting race.

RuneQuest 6 has centaurs as playable characters.
