I think the game could benefit by a racism, sexism, and classism pass for the NPCs.

One of my favorite parts of sky rim was walking past a condecding elf or an orc who didn't like my imperial character.
One of my friends played sky rim as an imperial working for the storm cloaks and got a different experience because of the feeling of being a distrusted outsider saving the day and being scoffed at.
Just the odd NPC reaction to your race or sex could do wonders for immersion.

With the explorers pack available players might be able to experience the feeling of being a stranger in a strange land during vet rank story missions.

Some suggestions for racism or sexism might be


Your player might receive a necklace gift in the mail from a secret admirer. If the player takes it and wears it, it activates an optional quest involving being stalked.
A stalker NPC who just appears in the same town as you, knowing about your adventures or actions. The already used mechanic of NPCs talking about your deeds might take a sinister turn if a stalker tells you he liked you in better in light armor or something like that. He could fill your mail inbox with unwanted love letters or jewelry. I dunno maybe there's something there maybe not. I'm thinking something like the fight fan from oblivion. Remember?

A slight increase or decrease in a merchants pricing depending on your race.

Random NPCs might remark about your race, class, sex, criminal history, or supernatural nature.

If players have the larceny skill line unlocked, NPCs might hiss and scoff as the criminal passes by.

And if a store owner was particularly offensive, he might falsely accuse a player of stealing even though they are innocent.

The guards would stop the poor accused player and the charge would be 0 gold, so the player could feel the fear of being falsely accused with no actual in game repercussions.

This mechanic might help to create and understanding about what its like to be hated, mistreated or just ignored because of your race, class or criminal history.

I know these are touchy subjects but their inclusion. Is part of what helped sell the 'reality' sky rim was offering.

The herbalist in white run noticed how pale my character was and always asked be if I had mud crab sickness. It made me laugh every time.

How do you think ESO could benefit from enhanced NPC reactions to your character?

Thanks for your time.
