Island map.

Peace and good to all! A little about myself. I play Heroes 3.58 (console version, without installing on the computer). I started playing in '99. The 4th game wasn't very good. The 5th one, I didn't like at all. I play on the 5th difficulty level (it's more interesting that way). Swamp Castle. Island map. I start with Voim, he has expert navigation. So he collects everything floating on the water while I'm short on money. My problem is this: to start a game with water, I have to go into the main menu and create a new game ten times. You choose an island map, and either there's only land, or there's practically nowhere to swim. Not ideal. Is there any way to get around this? So that the map has: 5-6 islands. Lots of water. And a Dungeon. I would like to play in tournaments or battle with those who want to fight me. Another question. I made a mistake with the login during registration. Can I change it? Because in the profile, I only saw that I can change the email and password, but not the login. P.S. I created a lot of clone topics. How do I delete the extra ones? Or moderators, please delete them. I wrote the text, clicked post. I was asked to log in. I thought the topic wouldn't be posted without logging in. I logged in, posted it again. I see that I have 3 messages. It turns out that I posted it twice without logging in. I apologize.
