What I’m looking for in an MMO (redux)

Yeah, I know I’ve talked about this before, but it came up in conversation during date night with Margie.  “What three things,” she asked, “are you really looking for from a game?”

I hemmed and hawed, and we discussed, and this is the (not quite three) list it boiled down to. It’s a bit less mechanics-oriented than the previous one, and more functional:

1. I need to feel heroic.  Jogging everywhere in the world? Doing boring grind missions? Imperiled by battling three opponents?  That’s not feeling heroic. (Note: this doesn’t necessarily mean “super-hero” or “comic book hero”.)
2. Duo-friendly. A big part of my gaming life is playing with Margie.  A game that makes it difficult for us (and usually just us) to play side-by-side, due to different start points, or poor leveling / sidekicking setups, or whatever, is going to be a frustration to us.  (Heck, I remain irked at CoH for quashing Level Pacting.)
3. A variety of content / replayability. I don’t want to feel railroaded through just one course of action. I want parallel ways of gaining experience and exploring the world and so forth.
4. Well-written content. I don’t mind humor, but overall I want to take the story seriously.
5. Alt-friendly. For whatever reason, Margie and I are both alt-aholics.  We like to try out different character types and combinations.  We’d like to play something (in conjunction with requirement #3) that doesn’t require us to delete characters in order to roll up new ones.
6. Soloable. Though we game together a lot, sometimes we like running solo, just to try something new, or because the other person isn’t around or doesn’t feel like gaming.  (This tends to be tied a lot to #4.)

So that’s more than three, but those are the important things I’m (still) looking for.
