Things indeed change. With each new surprise and encounter, the team and I think long and hard about how the things unfolding affect our vision, and whether such a thing would make the game less fun or enjoyable as a player.
The example in this case being Adam buying a second Kingdom. While he may have been the first to do it, he wasn't the first to offer or initiate the idea, so we'd thought about it before.
We're ok with it, because like all things in CoE, things are subject to change. The only constant is that tomorrow will be different than today.
If Adam wants to put $10,000 USD toward creating a single Kingdom which is twice as large as the others on a server of 4 or 5 Kingdoms, we're ok with it. While it may take away someone else's opportunity to put up $10,000 for a Kingdom, it's first-come, first-serve with respect to buying limited domains.
In the end, it creates a unique story on the server. And while some people are afraid of what effect it will have, if you believe we have given you the tools to depose someone who has become an emperor on your server through player actions, then we've given you the tools to deal with an emperor who set himself up to begin the 10-year story that way.
If you're concerned about us not giving you the tools to deal with such a scenario, then we should discuss possible tools and solutions.
But, claiming you'll ask for a refund if we allow something to happen is not the way to deal with this issue. Have a respectful conversation, explore possible outcomes, and ultimately trust that we're paying attention, listening, and care just as much about the success of the game as you do.
