You know what's cheap? Data Entry! I was watching
Blitzkriegsler's LP and noticed things like Mineral has Health but doesn't say it can be mined for Metal. Just UI-wise there doesn't seem to be a way to tell the difference between Mineral and Rock. Similarly when selecting things like Muffalo it tells you what the Muffalo is doing but not what a Muffalo is.
I think having a "description" field in the display when selecting things would be a valuable, cheap addition. For example, Mineral's description could say
"This can be mined for metal" and a Muffalo's could be
"A large herbivore". These descriptions could help new players get acclimated to the game. Also, if you wanted to get fancy you could parametrize the descriptions to make them different for different instances of a thing (like having fat/thin, large/extra large, wooly Muffalo).
