Damn, now we're talking with a pro hahaha
I'm still weighing pros and cons of what should be the next thing added. Maybe Edron, it would provide some good content until a high-ish level and could be developed quite fast. Maybe yalahar, for the same reason. I'll probably avoid Mainland for now even though that's way bigger and important, because at the same time it does not have that much content for a prolonged experience as any other continent would have and would surely be harder to develop...
Thanks for playing so much! Makes me less worried about higher level and skills breaking the game too much.
