Sueds :
Well i played WOW, guild Wars , but stopped : borring after some time :
Power up become borring !
I can't stop playing BattleField 2 so good in multiplayer :
some strategies, lot of fun, friends to follow/cover in team play
etc ...
I believe in Call Of Duty 4 multiplayer indeed : )

Manslayer101 :
An mmo : they are all the same
-show me some 6 very good different animated models characters and some 5 ennemies and 10 NPC as good quality as Guild Wars (that is becoming outdated even if beautifuul)
- show me 10 good terrain textures (not too dark/flashy) , 15 environment models (houses, btemples, structures, bridge,waterfall) and some 5 very good trees, 5 moving plants

Well don't start thinking mmo until you can't show us a quality as good as
Guild Wars that can make we dream
caus Guild Wars cost is really low and you don't pay anything per month.
I won't buy yours or play it if it is not lot more original or better
than Guild Wars !

think on that, before dreaming too much
I can bet in some two months you won't have 10% of what i've said
Sorry to be too bad , it's just to be some realistic some times !

Perhaps target a little RPG before thinking too hight
