Yes, it seems that either we are not working hard enough to promote large activity in the other houses, or that new players are usually flocking to Liberty because it's the first place they see. While that is a pressing issue, I'd like to see explanations on how changing the starting point for new players entirely could fix it. I think we can only have one initial starting point for players, by the code. So we would have no choice but to place it in one area.
Perhaps we could create starting systems for each house (including Outcasts and Corsairs) and link them all to Pennsylvania, with the same no full RP rule set? For ease of access and knowledge of existence, the gates/holes would need to be placed beside Erie.
