I see Sandblasted like the de_dust of MWLL.
It's one of the first maps released. It's also pretty much garunteed to run smooth on any system, and it has an easy to learn map synergy/design to it. A great introductory map, which is also why de_dust tends to be "classic" as well in Counterstrike.
Granted I've never been a fan of playing certain maps over and over, but I can always enjoy a game of sandblasted more than some of our more experimental map designs, like Extremity.
My personal Favorite at the moment has to be HelsGate. What an awesome map!
