Look at most Sci Fi series nowadays, and even going back some, you have races/species in abundance. Nobody blinks an eye at Klingons, Vulcans, Mimbari, Vorlons, Peacemakers and so on.

So, why have a problem with intelligent species on a fantasy world?

Sure, you have to have a reason for them being there, they don't just pop out of nowhere, or perhaps they do.

I like having different species, it adds flavour and a certain amount of exoticism that playing humans all the time just doesn't give you. When there are different cultures of the same species the game gets even better as you don't always know what they are going to do.
