It would be great to have a thumbs up, thumbs down system for worlds. A five star ranking system. Lately a lot of unfinished worlds have leaked into the game and more often than not with my friends I find myself checking out like 4 different worlds before we find something we like. It's a huge waste of time. It would be great to have the ability to rank worlds, having a top rated tab. So that way we can filter out maps that are low quality. A plus would be being able to write a review for a world as well.
