To be fair, everyone in GX seems to claim to WANT to be isolationists. All long-term plans I've heard from there involved pretty much this, focusing inwards and all. It's kind of ironic, really.
I've had experiences with realms wanting to be isolationist. Their players end up changing realms, pausing their character, or leaving the game entirely. Their ruling characters still clinging to their regions and titles. GX, don't make that mistake. Join guilds and religions with non-GX members. Interact with your government peers. Roleplay with folks from foreign lands. But don't cut yourself off into your own realm, realm guilds, and realm religion.
