We already have a thread for Survival maps, but I thought we should have one for any kind of map and server.
So, post your favorite maps and/or servers!
Some of my recents discoveries:
PARKOUR InfiniteCube 3
As the name suggests, it has many levels (108 I think?) and you get a random one every time you start a game. It's pretty fun, with different blocks that have different effects, and with a special level after you complete the achievements.
Just finished this map. If you've ever played Diversity, it's pretty similar. If you haven't, it's a CTM (Complete The Monument) map with 6 different genres: puzzle, adventure, trivia, parkour, arena and dropper. Not so hard, but not so easy either.
ADVENTURE/PUZZLE THIS IS NOT A MAP
Minecraft version of the THIS IS NOT A GAME game. I haven't played it myself yet, but from what I've watched, it's fun.
This map is awesome, but you have to play with 2 other people, unfortunately. It requires a lot of thinking, and it doesn't start easy (hency why the name is "there is no learning curve"). If you can't play it, watch someone play it on youtube, because it's really good.
