I just bought the game last Sunday and initially, it's a lot to read and understand. I'm still learning a lot about the game after 2 hours playing everyday. But take it slow and steady and you'll be fine.
I was thinking of putting together a "New to
TG Arma Pack" thread. With links to all the documentation a new person would need in order to get started. Right now there's way too much clicking around to become informed. I knew it would be a chore getting started so I was patient, but I'm thinking that if someone like my father bought the game (58 yrs old), he wouldn't know where to start. Neither would the avg FPS fan.
