Flyboys The Game
nice sim, you can play 13 singleplayer missions, based on the film flyboys, graphic is really ok, several aircrafts for axxis and entente are available , in the single player missions you only can get the nieuport 17.
for multiplayer-online gaming you must pay 13.95 dollars each month to sims..
otherwise its a nice game for evenings, cause no mission is similar like the other..
try it out!!
