This game has everything I like about RPGs and nothing I Dont.
I looked back on everything that anoyed me while playing wow... I hated when I was trying to do a quest, ones where you need to get a certain number of drops off of monsters or kill a specific number of a monster but had trouble doing it because of competition with a ton of other players on the same quest.. it was very anoying
I hated being ganked by rogues while minding my buisness and trying to quest, I hated being corpse camped by higher leveled players because they thought it was funny.
I hated listening to anoying general chat so I would turn it off in W.o.W. to quest in peace.
All these things I no longer have to worry about... And really, The fact that I dont run past people while questing anymore isnt really game breaking lol.
But most of all 2 of the things i disliked most about other RPGs were
having to find other players to quest with for quests I couldnt solo - Guild wars lets you hire AI controlled Henchmen to your group and all you need to do is share you exp/gold just like if you were in a normal group..
Also I hated the endgame of other RPGs where all there really was to do was PVP when all your quests were done but when you went to pvp you had to wait FOREVER to get other people to play with... Guildwars doesnt have this problem... The wait for pvp is so fast its great...
So yeah... Guild wars rocks... Its also free which is cool, though 15 dollars isnt that big of a deal. lol
