The only MMO I've played was Runescape. I played it for an hour before I said "This sucks," and then I left.

I win.

Runescape isn't bad, if you've

a) Got a HUGE attention span
b) Have NEVER played a p2p mmo
c) Got a credit card or means of payment
d) Again, have a HUGE attention span
or
e) Are under 10

f) you have no taste in video games
g) you find grinding amusing
h) you can put up with a community that has more jackasses than WoW and Xbox Live combined.

Shall I continue?

Please. I'm not stpping you.

OK.

i) you feel like playing an entire game based on the Barrens chat
j) you are a masochist
k) you lie awake at night wondering "how I mine for fish?"
l) you are trying to talk yourself into committing suicide
m) your name is Ternaldo
n) you tape every episode of Beyblades because the story moves so fast
o) you think CoD4 doesn't has gameplay

Wow. You feel very strongly about this, for someone who doesn't play MMO's
