Some good custom maps and gametypes?

A couple of my friends and I are looking for some good custom maps and gametypes for them. Does anyone know a good pair or two? (i.e. the Jump Rope map and game type; suggestions don’t need to be like Jump Rope, I just used that as an example of what I meant >.>)
