You can still focus on the plot and scenarios since that is a big project! But it is also the little things that make a game enjoyable! Again it is a small request and suggestion! If its offered to put in our ideas why not include the small ones?
It's just a small request please dont get heated at people who just want to see more representation! There is no place for anger just friendly suggestions
And why exactly you want representation in the different species of humanoids? There are humans in the game that can represent exactly you. Why all humanoid species should look like you?
