Considering how much diversity there is to human culture, you're probably asking the impossible. We've had everything from baby eating death worshippers to flower power free love communes... It would be nice to not have the French aristocracy and germanic tribes for the humans in yet another fantasy game though. Even just switching to the English longbow based armies and a new world culture for the token barbarian side would go well...
True... I think the main thing I'm asking for is not to have one culture for the entire race. If you had to portray the cultures of all humans on earth, you wouldn't just show someone European culture, you would show them the huge multitudes of various cultural beliefs and practices. I would like for a large portion of the cultures to be somewhat of a blend of various earth cultures if nothing original can be concieved of (since its really hard to come up with new stuff). If a single race can be summed up to be a representation of ethnic group X on earth, that to me seems very shallow as far as storytelling opportunities go. You shouldn't be able to do things such as:
Elves - Tall, pointy eared, immortal, first sentient humanoid race, use longbow, in touch with nature
Humans - Diplomats, warriors, relatively short lives
Dwarves - Short, heavy built, long lives, created somewhat on accident, axe weilders, build underground cities, created from stone
Orcs - Stupid, brawny, rush into battle, use crappy weapons, strength in numbers
Those are your basic fantasy steriotypes. The descriptions overall aren't to bad; they are rather unique when compared to human cultures. The problem comes in that there is no variety what so ever in how the races are used. A majority of fantasy fictions use the exact same steriotypes with little to no variation. The races are often not given much variation within the race as far as physical appearance, religious views, cultural practices, ect...
