Naming things in the game is a good thing. Places, weapons, characters, trade vessels, there's a lot of available customization. It could either be the use of the real name, of the making of a name over which you keep a say.



Extra content is also fun, as long as it does not create an imbalance in the game, but I don't think it would be a problem there. A new animal species (birds ?), a new weapon, even a new building/furniture, the game would benefit from extra content.



I would recommend avoiding physical rewards as much as possible, they generate extra overhead early in the game lifecycle, I feel like a small team shouldn't venture into those waters too early.
