Well the reason i took a LOONg break from PS is a MMORPG called Shadowbane . At first i was not really sure about it , since there seemed to be no RP at all , but then again the game provides a system where players can build buildings , towns , rule kingdoms , hire NPC`s for all sorts of purposes (indirect crafting if you want , as you controll the crafting functions of ..say the elven heavy armor smith you hired to the lvl where you can "tell" him to craft a "xy heavy breastplate of xy" . That will in terms cost money and resources ...a lot of resource types in game but that`s a different story) , then there is the part of sieges , player run guilds or nations (multiple guilds can unite to form a ation) can lay siege and raze or conquer enemy towns . Basicaly the game provides a lot of RTS elements from a MMORPG perspective...
well...enough allready...one last thing , it`s free ..
