feel you might need a 500 gigs of rarely ever played maps? is that ok?
a smaller list of the most played maps has been suggested to cover the majority of popular maps.. and the list may even exist..
after just a few days of playing casually you will have practically every map that people play and will need to download less and less.. i have to fetch maybe 1 new map every week now on my main pc.. people play the same maps allot.. zk is not as bad as 'ba dsd'
