As far as NPCs go I hope you will not make them overly aggressive. I play ylands because it is casual and relaxing. I understand others need more excitement, but I hope the characters don't make it stressful. I would like the NPCs to be generally friendly unless you provoke them. Maybe you could have occasional aggressive NPC's, or some only aggressive if you provoke them. I think it would be great if you could make the choice to either trade and be friends, or launch attacks.
Thanks so much for a fun game, and l look forward to the new updates.
