What is your opinion on the possibility of introducing a third tier of maps and a new faction into the game?

Then, all that remains is to present your idea to the Nival Interactive team, and if they don't accept it (the city – possibly, the level – I doubt it), then either abandon everything and indulge in nostalgic memories of "what a great idea it was!" – or still, make the faction an overwater one – or do everything yourself, which is the most difficult, especially with the current plans for a new level.
