There is a new game out called "Rise of Flight." Its composed of WW I planes and missions. It is written and distributed in Moscow, Russia. I believe you can get a trial subscription.

There are still bugs to the game, but I am learning to work around them until they are resolved. I consider this game very difficult, to say the least. I am flying at its easiest level, and still having a hard time staying alive. Most of the time I fly into the ground on a convoy attack. But, being an old WW I airplane buff, I'm staying with the game until I get the hang of it.

Its another option that's available for at home or on line..
