If it would be cool, in your opinions, would it be popular.
This should go in General Discussion because you aren't really suggesting or requesting anything; you're just asking for opinions regarding an idea of yours. You would also get more replies because that section is viewed more often.
Anyways, I'm not really into RPs, even good ones, but I don't think I have ever seen a Colonial RP. If you could pull it off, it would be pretty cool.
I would rather it be less of an RP and more of a survival type thing. Like everyone in the server is given a role, like hunter, gatherer, lumberjack, builder, fisher, etc. You would have to build up a town and survive. Although it would be pretty difficult to do, it would be awesome.
