WELCOME ABOARD!
As stated above, it isn't meant to be a simple game where you run around and shoot things. Even the earliest of this time of sim required patience and planning. That said, learning how it was actually done and learning some history along the way can be highly entertaining.
The biggest thing to remember is that everyone here started off not knowing how to do most of it, and those of us who are still here truly love it. And we are here to help folks like you to learn as well, because we want you to love it too. So try the game, take note of exactly what you're having trouble with, and you'll find a lot of friends who want nothing more than to help
