NvS is awesome but I strongly recommend doing it with a bunch of mates and make a long weekend of it. The Sunday game is only a fraction of the experience, there's loads of activities plus of course the camping fun of drinking and burning meat on the BBQ. The site is massive so you have to be smart and find out where's the best place to go each time you spawn. This last year the generals did a great job of setting up contact and rally points to feed orders and the minibusses that Warped put on were awesome. Most of the people I saw moaning about the walking were too dumb to pay attention to how the game worked and all the resources that were available to get around.
