We want to be sure that any new features—even the ones we're testing—make the right first impression. To that end, we decided to start our experiment in North America, where most of our developers live. This lets us quickly react to feedback and efficiently implement updates on a regular basis. With the location locked in, we considered what would be best for players. As much as we wanted to open the doors to Agents from other regions, the resulting latency would ruin their experience and make it difficult to gather good data about new content.

While there are other reasons (cost limitations, network logistics, etc.), we ultimately chose the path that would provide the best experience to a limited group of players, so we could use what we learned to benefit Agents around the world.
