Classic Fantasy Races

Dwarves - drink more than they eat, rarely ever drunk
Elves - vegetarian diet, get drunk more frequently
Giants - take up 2 instead of 1 spaces at a single table, order multiple rounds
Orcs - engage in tavern brawls more frequently (if this ever becomes a feature)

These races could also be playable. Enabling some of their appearances as cosmetics for the playable charactery. Especially elven ears or orc skin could be possible (I assume?)
