1. For black forest map: The map is somewhat wide but not very long and looks like a black forest ofc. The feature I was thinking of was you cant see anything except for a small amount of blocks around you. Though I dont know if some will find it more annoying than interesting.
2. I have not thought of a name or map but did think of a special feature I guess you could call it tnt wars on a budget, basically you start with limited items, dispensers are prefilled same amount but you have 20 dispensers. 2 water bucket uses, 32 stone bricks, 32 redstone, well that's for example the actual amount I think should be decided in suggestion thread if people like the idea. If you run out of items to use you wont be able to grab anymore til a curtain amount of time has passed not a super lengthy amount of time though.
3. A sui focused map somewhat midrange distance between sides so it's not like to insane. The map itself should not be to big though. As for how to get people to make suis simply remove the water bucket on it. Though if u have better idea for a map for this pls mention in thread.
Thats all I got rn honestly.
