One of my hobbies is playing the Everquest 2 MMO. I've got 4 (soon to be 5) characters at max adventure level, all but one of them able to raid. I've got 5, working on 6, max-level crafters. And somehow, despite starting off as a tank, I've fallen into the role of healer. Mainly, I think, because I actually concentrate on healing and curing when I'm playing my healers, instead of trying to DPS. At the top end that makes a huge difference, because there's a lot of stuff where if you don't cure it quickly (within a couple of seconds) it's going to wipe the entire raid. On the technical side, I've taken over maintenance of the ProfitUI user-interface mod. Mostly this was self-preservation: I use ProfitUI myself, and with the previous maintainer leaving the game I either have to maintain it myself or go through the hassle of changing UIs. I know the UI XML well enough, and if I'm doing the work anyway I might as well make it available to others.
Why do I play an MMO? Because it's a game where I can socialize with friends. I don't really get addicted to games where it's just me in front of a screen with no interaction with anything except the game. The attraction of MMOs is that I'm in a group with other people I can (through chat channels and voice chat) actually talk to while we're playing. And when you get anywhere from 6 to 24 people grouped together doing things, there's a surprising amount of management that goes on. Someone has to keep the whole force doing what they need to do, reacting to cues correctly and generally keeping to the plan. That's not easy. In fact it's a lot like herding cats, except cats would be more organized.
I've tried other MMOs, but they just don't catch my interest. World of Warcraft, Star Wars, Vanguard, Guild Wars, Rift, they all just seemed... meh. IMO EQ2 has the biggest, most well-developed world from a standpoint of lore and storylines, and the widest variety of paths you can take while advancing. It narrows down more at the higher levels of the game, which I don't like, but it's still the most interesting and entertaining of the fantasy MMOs out there.
Attached are some assorted checklists and spreadsheets I've made for different things in EQ2.
The most useful at the top end is probably the Adornment Types spreadsheet covering most of the various types of adornments you can get for gear. It lists the crafted and purchased adornments and what slots they go in, and it's arranged so you can use it as a checklist or planning sheet when figuring out which adornments you want.
The Gear sheet I made up so I could jot down what gear my characters had. I need to expand the columns for armor to include more of the T9 raid armor. When I made the sheets I didn't have access to the set lists so I didn't know what was there. I tried to organize the set columns in order so going left-to-right you see sets in upgrade order.
