i used to just collect the pieces (i would do the one that goes with meerca chase, i also have a guide for that game in the guides section, lol) but i would collect them, thinking i could eventually get a whole map set for free, but it turns out that it takes for frigging ever to do that, especially playing only one game 3x a day, anywho, after like a couple weeks or something i'd break down and buy the rest of the pieces of the map, and the duplicates i had, i'd sell, doing that i usually made some decent profits after a week or so (i also undercut everyone else selling the pieces by like 500-1k NPs)
