I have been playing an MMO WWII Navy Game for a while now, that you guys might be interested in trying out.
Go to http://www.navyfield.com/ and check it out. It is history based but not historically accurate. You can play for free, but paying accounts get XP bonuses.
The only real down side of the game is that it is kind of a long grind to get to level 120, but by joining a fleet and playing with friends it is not as long.
In addition to regular battles there are fleet tournaments and Harbor Assaults where fleets take on each other. We use Teamspeak to chat with each other while grinding, but especially during tournaments, and fleet events.
I play as Sirgurd on the Missouri server, and I am an officer in the Red Sky Fleet. If any of you guys try it out, and decide that you like it look me up, my fleet mates and I will help out any and all of you. Our Fleet web site is http://www.redskyfleet.net/v4/ . If you apply mention me.
So give it a try and let me know what you think.
