I have the sudden inspiration to play as a toned down HG Wells style Martians here.
Would that be alright?
Say, some decades ago the Martians landed on a certain country and conquered it but currently they lack the resources to advance any further.
They wouldn't  be OP in a steampunk settingabd they would be even open to some diplomacy here. Though the fact they keep humans as slaves would make people somewhat apprehensive to them, no doubt.
