you're like me. I enjoy MMO until end game becomes excessive, and then I get bored. MMO "success" is mostly about achieving something with the endgame. I tend to get to some point where I'm satisfied, then give up.
PvP has never been my thing in any flavor, and when team PvE content gets serious enough in guilds where you start to schedule time to accomplish dailies, and then that doesn't happen because no one can do it, I just say kitten it and stop logging in.
yeah...i managed to get in an awesome guild in Rift. Was all adults, all people who understood that we all had lives outside of the game and everyone got along for the most part. I started to get bored doing the endgame dungeons but enjoyed hanging out with the guildmates. we ended up running around together just doing achievements for awhile because slowly fewer and fewer people would log on to do anything.
I quit before some of the people I liked the most. wish i would have kept in touch with them to see if they went to other games. I haven't found that in any other game since.
Everyone says they hate the fantasy mmos but I think I like them the best. I also like the "old school" type of MMO, not this new fancy "active combat" crap. I have enough trouble remembering what skills to use and when to have to worry about constantly moving. Rift had some of this but it was only in the dungeon bosses, so it wasn't too bad.
Never liked PVP in MMOs either. Usually because I'm fighting against people who spend 12+ hours a day on the game and they're way better geared than me so it's no contest. Either that I get ganged up on.
When it's open world PVP, it's even worse. My 1 attempt at open world PVP in WoW sucked. Constantly getting ganked by a GROUP of people 30+ levels than me and then they'd sit there and wait for me to resurrect so they could do it all over again. Meanwhile I'm just trying to do a quest...
