Guild Wars was a great game, probably my favorite MMO of all the ones I've tried. (I'm playing LotRO these days.) GW was the perfect game for people on a budget (no monthly fees! Yay!) and/or people who like to solo (having NPCs/heroes available for party completion was just plain awesome), combined with a beautiful world, great stories, exciting and creative quests.

However, right now it looks to me like SWTOR may overtake and overshadow Guild Wars 2 entirely. They are sounding alike in many respects:

--persistent world
--solo friendly
--customizable companion character
--story-driven

If they end up going up against one another, I think SWTOR had the edge.
