But it still helps-it showcases maps. This game has thousands of maps
The main problem with current MotW is that most of those thousands of maps have already been nominated years ago. And once a map gets nominated, it can never be nominated again.
Since less than five new maps get made every week, we're close to running out of maps.
I'd love to see a MotW successor where old maps can be re-nominated every once in a while - then, as you say, players can again discover a lot of good old maps through the Map of the Week.
