Okay, I had some feedback on the Discord and the impression I got was that a few people are confused about what exactly I am proposing here. The only thing I am truly committing to is explained in the first sentence of the thread: "I'm hoping to start a conversation about the international role-play in the game at the moment". The purpose of this thread and
the associated Discord server was primarily to get some discussion going on international role-play among those players who are interested, in the hope that would lead to some progress or cooperation. At this stage, I am not committed to any particular proposal.
The "bipolarity" suggestion that I made was just an initial idea and something to get a discussion going. When it became clear that my proposal had some flaws, I reformed it into a "tripolarity" proposal. The problem with much of the response to these ideas has been that people are far overestimating what I was proposing by a "bloc". I didn't necessarily mean a military alliance like NATO or a political union like the EU, I simply meant a loose association of nations which could be connected in various ways like trade deals, friendship agreements and maybe down the road more substantial arrangements. Likewise, the polarity terms weren't intended to represent strict understandings of international relations, they were just a shorthand way to reference what I was proposing.
Another point of confusion seems to have arisen surrounding what the fundamental aim of my proposal was. I think creating a map may have encouraged people not to read my posts as thoroughly but they were never intended to reflect the existing state of Terra, they were an objective that we could work towards. The principal goal was to establish an ordering principle or a common destination so that when we are conducting international role-play we're all pulling in the same direction.
In terms of moving forward, I still think the divided Terra idea is plausible although I did wonder whether a "spheres of influence" approach may work better. Perhaps the Third World could essentially become a game of chess for the Great Powers who try to establish sympathetic governments in each nation? I'm still eager to hear other players input both on this thread or the Discord server.
