At first I thought new races would be a bad idea, but then I realized they could add a lot to the game. So I came up with four new race ideas:

Ogres - Look like humans but big and fat, live in yurts and have smaller populations but with very powerful warriors that can smash multiple units at once, don't like elves
Ratmen - rat people that live in shanty towns with massive populations but they are all really weak, fight with huge swarms of weak units, can also spread plagues, dont like goblins
Lizardmen - aztec inspired architecture, they function similar to elves, don't like ratmen
Goblins - like ratmen but with more ocish architecture, they don't like dwarves.

in my opinion the lizzard men should be a very slow expansioning faction but they can make golems that are stronger, faster and more efficient than the lizzardmen.

and the goblins would be able to throw their sticks to deal damage, and they would have the ability to hold multiple weapons but only use one at the cost of only being able to wield sticks

half of these are from a mod just get that
