While i enjoy all of the above, that is strictly a byproduct of the fact that thats really what mmorpgs are designed to do, and thus doing anything in an mmorpg would result in one of the above things being done. A strong motivation for me, and what has most likely contributed the most to my addiction is working with other people and existing within a perfect and efficient group. The aims of this group are not important, we could be grinding or camping a spawn to get an item for someone, when everything goes perfect, no communication is needed, and everyone just does what they should exactly as it should be done, i just feel great. While i would much prefer to follow a good group leader, most the time, as i usually play classes that are able to control the flow of a fight and thus require greater situational awareness to even play than more straight forward classes(that is, a bad warrior can still kinda function in their role if played badly), i end up being the leader. It just makes me feel wonderful when my group does something other groups are not able to do. Back when i was playing daoc me and my friend had made a pally/minstrel duo and took out things that most people said you couldn't do with even a full group... it made me feel good. This has been a great source of joy and frustration for me, because even if things go well when a group member is not doing something right i get agitated and an argument is likely to break out... people just don't understand what im upset about. Conversely if we wipe but everyone was playing at the best of their ability and every little trick had been done, while im sitting there waiting for a rez i still feel just grand. Interacting with people and being able to depend on them, and be depended on by them... that's why i play. [WoW, M, 20]
