Good Lords, Fair Ladies.
We're very pleased to hear that you enjoyed the large maps in Sandbox (even though they take a bit longer to load). There have been so many requests from you for map presets of similar size in other Diplomacy is Not an Option modes that we just can't help but comment.
Developing Challenges and Endless Mode versions takes some effort from the game designers. Yet they (the game designers) are busy right now with the story campaign. Nevertheless, having received feedback on the June update, we made an important (and fairly obvious) decision...
Ladies and gentlemen, large maps will show up in Endless Mode, as well as in Challenge Mode. The question is, when. We're not ready to announce the exact date yet. But certainly, before Diplomacy is Not an Option leaves Early Access.
Yours, the Door 407 team
