Ghost Recon is a somewhat older game, which shouldn't frighten you as Half-Life and the Counter-Strike mod are how old?! Just like CS, GR lives on despire its age because it's a great game and has an active modding/mapping community, but the real draw for me comes from the Tactical Gamer players and the immersive manner in which they play GR:
verbose: "Contact. verbose here, I have a patrol of three due West, approximately echo-niner, moving along the echo line. Will be danger-close soon."
leader: "Charlie squad, do you all have eyes?"
charlie1: "no eyes"
charlie2: "visual"
charlie1: "moving..."
charlie1: "eyes on all three now"
leader: "Charlie you are green to engage in 3...2...1...fire."
They take GR seriously, to the point that speaking after you've been killed in a mission is a grave no-no. You're dead after all, and the dead just don't report enemy positions from the Great Beyond. Yet, they're all playing purely for fun, and have proven to be a overall great bunch of guys and girls. Yeah, girls play tactical shooters. Beware boys, Luna in particular is not only good enough to hand you your rear, she's also a GR admin, and is quite frequently voted to lead missions because of her ability.
If you desire more teamwork and realism than CS can ever hope to provide, and would prefer to crawl through brush before planting a bullet in the back of a sentry, instead of charging him with your gun blazing, Ghost Recon or Raven Shield may be right up your alley. A few words of warning though: Your odds of finding a populated game of GR at TG are much higher than one of RvS, mostly because far more TGers play GR. And of greater importance, while there is a public GR and RvS server, the GR/RvS regulars are almost all TG paid-membership folks who play primarily on the private servers. They will, however, frequently jump on the public server to play with non-members, especially for visiting teams or other public regulars who have been known to be pleasant.
If you want to try GR or RvS the TG-way, without dropping coin on a membership first, I'm sure a post in the appropriate TG forum would be plenty to schedule a time for an in-game introduction. Probably better to do that than to hang out in the public server and hope some players come along. I'm not a GR or RvS admin, and I honestly haven't been playing either game for too terribly long, but I'd be glad to provide a hand in getting any interested person started.
