Went back to a VERY old game (PC) that has just been released on Steam. WWIIOnline. This game has outdated graphics (by a decade), and an incredibly steep learning curve. But man, it is fun once you get into it. if you're a fan of team play and strategy, and don't care too much about graphics, and are a fan of the WWII genre, it could be a good game for you.
I played it when it came out way back in 2001 for a few years, dropped it because of life, and went back to it occasionally.
It has so many things you can do. And so many different types of each. You can drive a tank, a truck, re-supply, fly a fighter plane, a bomber, get on a boat or destroyer, man an AA or AT gun, parachute from a plane, destroy bridges, build bridges, dig foxholes, use a bazooka, capture spawn pints or army bases. All things are player driven. Small amount (miniscule) ai that guard far away cities from attack while the map is progressing. You can play German, French, British, and American (American army only right now).
