Not so sure on the RIP il2 ,you can fly online wars on there and for a sim that is 10 years older and with the mods not really a huge amount of improvement on CLOD,well not 10 years worth.
Ok some visuals are better but not 10 years worth of better,oh and il2 is playable on older PC's for those of us who won't or can't upgrade for 1 game.
