I wanted to start a discussion on what kind of consequences the (sub)race of the PC people like it to have. With this I was thinking about reactions from NPCs about, but also item restrictions for example.
I think most people will expect some kind of realism in the responses from NPCs. Some communities or regions are less stranger-friendly than other, some indivuals might be openly racist, while others are but won't say it outloud and some think they're not but actually think a lot in stereotypes. Ofcourse the way it's handled in the setting can make a huge difference.
However do expect to get denied access to buildings because of your race? or that of your party members? Get more quests offers because of your race, or more specific kind of offers.
Do you expect race restrictions on romances? Maybe party members only willing to join with PCs or certain races.
And do you think the racism should be more or less equally divided? Humans hated in the first town, dwarves in the next, etc. Or one race egtting screwed over through the entire campaign?
And do you expect each set of armor to be tailored to a race? I don't think it's very realistic that a dwarf and an elf can wear some piece of armor. But having a race restriction on everything can be annoying.
Personally I think it hads a lot of replayability, it's fun, but better to keep it to limited area's of the game. This because of it can very annoying to miss out on a lot in a playthrough or be very restricted by the character you love so much. With campanions I'm all for it, maybe not refusing to join PCs of one party, but being more judgemental or quicker to leave the party based on PC race.
