Here's a guide on how to generate a random map:
1. Place the desired template in the data folder and rename it to "rmg".
2. Open the map generator, then click File -> New.
3. The generator menu will open. Click the checkboxes for "The Restoration of Erathia" and "Create a random map".
4. Next, customize the map as needed, including underground areas, the number of players, water, and monster strength.
5. Replace the red and blue castles with random ones if you want to be able to choose castles when creating a game. In Diamond, you'll have to change all the castles, lol.
The problem is that the map is visible when creating it. Either you have to use third-party services, or both players look at the map and decide whether to play or not. Either way, both players are in the same situation.
Then, save all this mess in the data/maps folder of our remake, and play.
