So, as for playable races, I was thinking this:

1. Humans (duh)
2. Androids
3. The Valkyries (winged humanoids with electric powers)
4. Amazons (which here will be an all women race of plant people)
5. Satyrs and Centaurs (they're the same race)
6. The Draco (reptilian people)
7. Mermaids/mermen
8. Dwarves
9. The Yukites (ice powered spirits)

How does this list sound to people?
