Good article, good writing. I would disagree with the first MMO however. NN was not an MMO but rather a game with online play. It wasn't massive like Ultima Online was in 1998.
I play GW (I'm one of Buc's guildies) and I also sometimes long for that unforgiving pvp as you described Droniac. I played on UO's pvp server for two years and it was a lot of fun but as Buc pointed out, there's a lot more drama too when it's a free for all and you can be looted.
The other problem with that form of pvp is there's no clear winner or loser, it becomes like an adult version of guns where you and your friend argue if he shot you or not. Then it spills over to the fan forums.
I think that's why I went with GW, when the fight is over I've either won or lost. Hard to spin that on a message board.
