Hello,
i second that - while i have been playing OFF i would have liked to also get my hands on RoF, but the online requirement along with paying for every additional plane was too much. Played it at a friend's PC for a few times and even if the aircraft models are superb, the "action" and lacking campaign was sobering.
But it's true, you have to pay for every plane apart from 3 or 4 (?) included ones, and internet-connection is a must. What especially pi**ed me off was the automatic download of new 600+ mb patches if you just wanted to play a short mission

But i'll buy it anyway if they drop this online bullsh!t.
Let's pray UBI does not follow this way with SH5 ..
Greetings,
Catfish
