Even when the game was still active, I always felt more drawn to it in the spring and summer then the winter time.
Maybe because it was always summer time in Paragon, I would just love to log in and hang around the city - even if I didn't do missions or anything, just chatting with people or selling stuff or going some business in WW.
And that's what I miss the most - it was more then just a game - it was a community of people to chat with, a place to just hang out if you wanted to just hang out.
Icon helps a bit by at least being able to wander around the zones, even though it is a ghost town.
Its too bad there isn't a way to get some action in the city, even if it is just for a local session, but I know the main guts of the game was run on the server side and not local.
