I've been playing- and enjoying- Factions. After a year of Prophecies, I find the added elements and different feel to be lots of fun (mainly PvE), and a welcome change of pace. It also has increased my appreciation of the original campaign.
Factions was positioned as a standalone game. And since you can play it by itself, it undeniably is. We can argue all day about whether it has the same amount of content as GW:P- that's not what I am here to talk about.
My question is- should C3 be an expansion or another standalone? I am assuming it will be like factions, but what would a GW expansion actually look like? I would not mind seeing a release that just contained content- I don't need new skills, professions, continents, etc. in every chapter. I wonder if Anet will at some point do a release that is an expansion on the original prophecies campaign- I'd love to get the Char out of Ascalon, or explore more of the lost city of the gods.
I suspect that Anet will continue to position their new releases as new standalone games- they can charge more that way, and I suppose it lowers the barrier of entry (you don't need to buy the original game to play).

the answer is clear.
