DomoCatFaceI didn't speak to enough people my first lan and I really regret that. Come to the bar on the evenings when the games are over and don't be afraid to speak to some people you recognise, you'd be surprised how welcoming everyone is even if they don't know you.
Gotta personally agree on that one and I've heard it a thousand times from other people
Important shit:
Don't forget to eat 3 times a day, big hearty breakfasts will be a life saver
Don't forget to hydrate, just do it a fuck ton just to be sure
