One day I should surprise myself and play either Morrowind or Oblivion with one of the game's vanilla races

I agree about custom races cartowheel, - I like to be able to play a game with a character that is a fit for my mood or personality & etc at the time and most of the vanillia offerings don't really suit me. Oh my memory has creaked into action and I must confess that I did play as a Bosmer/Wood Elf once in Morrowind, but after that it was all custom characters I'd created myself.
Roleplay is a major part of my gaming experience and by doing that a custom character that I've created might seem overpowered on paper, but in roleplaying their essential character and personality they don't actually have that much of an advantage.

I run a Bandit War mod with Oblivion which is basically four large gangs of bandits struggling for supremacy in the land so bandits are everywhere, in groups of more than two and are often well equipped. I'd let that fact slip my mind so when Shanna Two Spirit stumbled upon three bandits at a crossroads when ze was only lightly armoured and armed with zir wooden sword and shield I seriously had my doubts that ze would survive. BUT ze did! - proving that once again a not especially strong character with good speed and agility stats can successfully take down better armed and equipped opponents. Shanna's wooden sword has good reach and durability, but its striking power is nothing to write home about. It does have a small enchantment though that reduces Luck by two points with every strike, - which is a classic example of Two Spirit people's approach to defending themselves in general.
It wasn't a walk in the park though and the fight was well drawn out before Shanna won through with plenty of zir blood lost and bruises to go with it. And being Two Spirit ze didn't loot any of the bandits' gear that was made of metal apart from a few gold coins.
Here's a picture of Shanna at home. There are some great Treehouse mods available which saves me having to make one because they are always complicated to put together from scratch.

And finally here is a picture of Shana with zir clothes off. Please bear in mind that while I'm happy with the face and body textures I still have work to do on the upper body mesh.

And finally a close up of Shanna Two Spirit's face and zir stats as at level 2.
