I played UO for probably 10000 hours over the space of 14 years and will probably play it again in the future. Also, Pangya, which wasn't a very well known game, I must have logged at least 3000-4000 hours before I burnt out on it. There were many people who did the same for all of those games. I'm sure many people played thousands of hours of WoW (a game I didn't enjoy). 100+ hours for any gamer is the sign of a pretty good game, but I was more wondering if people will play GW2 as their main game. Spacing out 500 hours of gameplay over multiple years isn't really the same thing I was asking - but I did get answers.
The population of GW2 doesn't seem that high for how new it is, it will be interesting to see if it goes up or down at this stage. I sPvP all day and the game browser probably shows that there's less than 500 people playing at any given time (out of 2-3 million copies sold? That's 0.02% of people who bought the game in sPvP at any given moment). Obviously ANet were expecting more, because there are literally hundreds of empty game servers. There are more people logged on to a free Ultima Online server I play.. a game that came out in 1997.
I guess my point with what seems to be conflicting points of view, is that I really enjoy this game and I want to see it succeed in a certain way that it doesn't seem to be currently doing. I'd love to see the PvP become a great esport that people like to watch. Maybe I'm just pessimistic though.
edit: there's currently just over 200 people in spvp. There are more people playing CounterStrike source in New Zealand alone O_O
