I've been playing the PvE for...a bit less than Ush has. Still nearly a year now, though. And there is tons of stuff I've yet to do. And that's just with my main character. I have 6 fully leveled up characters in varying states of game completion I will be busy with the PvE for a good long while.
The graphics that we saw in the trailer were still amazing. And it's still a ways out from the game's release, too. It will likely look better by the time it comes out, and ArenaNet has always said, as Ush said, that it will be designed to run well on mid-range computers. Frankly, it was beautiful. Though GW1 is still amazingly beautiful, and it's an aging game.
PvP has never really been my thing, though the professions I like the best (Dervish and Ritualist) are really not very good for it. Though I'll always be amused by the time I decided to go into Random Arena with my Dervish, faced off against a group of 4 Dervishes (all using avatars, which is just dumb in PvP), and shredded all of them. Or shadow-stepping in Jade Quarry. Hehehe. That's as much as I do, though.
I agree that the basic focal point is the PvE, but for me interaction with other players is really important. I find it a great experience to play with other people, and I can't bear to play with henchmen and heroes. So I PvE'd until it was bearable enough to get a group, but after Eye of the North it was just impossible.
I can also see how people don't like PvP as much as you actually need all of the expansions in order to be at least a tad bit effective. The money that you would spend in order to buy all of the expansions is pretty intense to say the least. I bought them gradually, so eh.
the thing I loved about guild wars was the clever skill design.. it really felt like they put so much thought and care into each one.. made it a joy to try them all out
skill implementation was awsome, well, through Prophesies & Factions, With the introduction of NF they lost a bit of balance with their Hybrid Professions (loved the campaign - hated the new classes). But for me what made the skill system shine was the limited skill slots. It added a whole new level of tactics to the game.
Ooooh. I hadn't seen that thread there yet. I've seen some of the things in there, though, and somewhere (I found it last night) there are scans of that artbook.
That intrigued me as well. Especially combined with how the lead of the live team said that she wants to do more small content updates instead of big ones like in April.
(I'm surprised you didn't comment on the dragon-infected hippo line!)
