Star Wars Galaxies is one of the best gaming experiences I ever had. I truly believe that game got closer to what a MMO should strive to become.
This was a broken game. Combat, pvp, quests, progression, balance. It was in despite of all these flawed things, that the game was a tremendous success and breakthrough, in other areas (community, player run economy, player build cities, innovation, individuality, customization,)
There was another gameplay system that complimented the crafting. The resources system. You wouldn't just gather materials in the world. Every material, would be of a certain % purity value.
Meaning, to strive to make the best houses/droids/armor/starships/weapons, you would need materials with the highest %(highest being 100%). The thing with that? All these materials spawned randomly around the world with varying values.
For a person who spend all his points in crafting, he would have to rely on other people to gather him the best materials in the world. But no guide could be written when a randomized system governed the quality of everything, and since everything was build by others players, you where dependent on other players to sell, trade and buy from. Shunned if you where an asshole, the game had other radical ideas about what a community could be.
This was one hell of a game. And nothing has been like it since.
In contrast to that system, GW2 has a more simple straight forward crafting, but in GW2 it is instantly rewarding. It's a great system, in a different way.
