I see a lot of talk about need for new races. I personally would say the Hearthlings are like most “Halfling” races, a combination of both. I would far more prefer falconry, bears, deer, residences, cooking, fishing, pharmacy/alchemy, and effective roof design and rope. We already have one people. They are a handful and while I would love to see other variations. Giving them unique properties is one thing, but in this game, properties are driven largely by class. Make a class that has the ability to climb trees, or control the undead - temporarily. Make a class that can draw the power of the sun down and enchant items for buffs. Make seasons so crops have to be cycled and you have to prepare for times of scarcity and shelter from the elements.
I am intrigued heavily by this game, and would love to see THIS people grow into their own. I am just not sure what forest people or cave people bring to a world where the people already comb the forests and mountains for any sign of their future they can find. Elves and Dwarves are great lore. Make some abilities connected to discovery of relics of these once noble people. Make an archeologist who unlocks their mysteries to grow the other classes from the base few. But first and foremost - don’t lose the HEART in hearthling.
