He might add more of them in, maybe he can also add the Import and Export feature in the game as well just so that the player can have whatever items, levels, and stat points was added in the game without starting over fresh?
Thanks! I'm glad you like the game, I'm happy to hear it!
To answer the question, yes. I'm planning to add relations with other species too. In 0.11 there will be a new satyr npc. Lizardman will also get some love eventually. Plus I plan to add other species too.
