Personally i love a good challenge. But PVP has never been that fun for me in a role playing environment. When i want to play PVP i play cod or some other shooter. When im playing a role playing game i want story, character development, and of course L00T. Also being killed repeatedly by characters 10 lvls higher than you will ruin your fun. Thats not challenging its annoying. True open PVP games will never sell on the mass market in an MMO because, who wants to drop a monthly fee just to have some 12 yr old with nothing better to do kill u and steal all your stuff. I would like to see some PVP stuff based around guilds and factions. THat would be awesome. But just straight open pvp would be pointless and would lead to alot of griefing, as for having one character per account, i really dont think it would sell well that way. People like to have choice, for instance i have anywhere from 2-5 games in progress in fallout 2 at any one time, each with a different character. And then i play whatever one im in the mood to play at the time.
