Every time I see a screenshot or video of Guild Wars 2 I'll either think it looks amazing or think it looks like a game made in 2005. Especially coming off of the TERA beta, a lot of the art in GW2 looks flat and plain in comparison. Am I to assume a lot of it is because the game isn't finished yet? While I can see validity in that argument I don't think it's as simple as that, I don't think they'll be able to update much besides the spells and abilities before the game ships.
I guess it's a limitation of the engine? TERA was using Unreal, which I guess would explain all the pretty curves and shading in everything. Guild Wars 2 on the other hand seems to use a lot of flat details mixed in with the 3D artwork, it's really easy to see the seams of the engine and where they were counting polygons.
