On MMOs

Everybody seems to be playing one MMO or another and then, there's blood-chilling stories about breaking families, hikikomori individuals and other anti-social misbehaviors.
I honestly tried several times to get into at least one MMO to see what's so wonderful about them.
I tried many of them, including Ragnarök Online, R.O.S.E. Online, Dofus, Tabula Rasa, Gaia Online, World of Warcraft, Lineage II, 真・女神転生IMAGINE, Battleforge, Neo Steam and now - Guild Wars (there were a bunch of other games, which I can't remember, too).
And I can't get into them... like at all (well, Guild Wars is still downloading). Best results so far - Megaten, which I've played almost 5 hours across half a month.
I am inclined to blame my preferences in gameplay style. Which is single-player. I'm seeking role-playing side of MMO in the first place and with my chaotic play schedule it is virtually impossible to have a solid group experience.
That being said, I'll try Guild Wars and see if it will suit me. Also, Final Fantasy XIV is promising well-balanced single player experience, so I look forward to it too. But the thing is, that I am still prefer classic offline games best.
PS: also, a big thing about me disliking MMOs is their anti-cheat systems, which in most cases completely prevent me to even launch game (incompatible with 64-bit OSes, Vista+ and most anti-virus and firewall solutions). In that sense, I hate GameGuard and X-Trap, which is really a pieces of crap that is unable to run on my machine. Oh, sad reality...
