Well, in Guild Wars and Guild Wars 2, you also have reasons to collect lots of the same stuff to do stuff.

The difference is that you don't have to collect 10 boar asses in boar ass forest for a specific boar ass quest, but instead you may want to craft a legendary bone weapon, so you need to gather bones, and you can go anywhere in the world that drops the bones, or that gives gold you can use to buy the bones from other players, or that grants a special map currency that you can use tyo buy boxes of bones from a map currency vendor, all while doing whatever you feel like doing, progressing your bone gathering in a wide variety of ways.

Guild wars 1 and 2 are good games. The second one is still very active.
