Gaming is a multi-billion dollar per year market. Many of our future warriors are in training right now and don't even realize it with games like the DeltaForce series, Battlefield 42 or my favorite, Desert Combat.
Too bad the Delta Force series is finished and replaced by a piece of crap called "Joint Ops". As for BF1942, it was the biggest waste of money I've ever spent on a video game.
Actually the first person shooter games have really gone down hill lately. They all seem to be tilted either toward arcade like action or total realism. Games that are all one or the other usually suck. A balance is needed between them.
I haven't enjoyed the DF series since DF2 became cheaterville and never found a game I really liked since then except for WWII Online. I'd play that but I got a lifetime ban for voicing my opinion to some changes that were coming even though they specifically asked all the players for their opinions.
