I personally think that it would be cool to have many races that greatly affect game-play. Such as Dwarves, Elves, Orcs, Goblins, Etc. All having an impact on how the workers complete tasks. Such as Dwarves have a faster Collection speed / Building speed, but are slow and do less damage, Orcs doing a lot more damage, but greatly affecting their building. I do know that this game is VERY W.I.P and this would take a while, but possible during beta this could be implemented. Also, If you guys are looking for a Alpha/Pre-Beta tester, i would be more than happy to volunteer.
