I bought cliffs of Dover yesterday on the bargain table and all I can say is its a stupid piece of crap.
I love that game, it's excellent. Especially with all the realism turned up, just getting into the air feels like an event.
The only reason some people from AcesHigh probably don't like it is because of the lack of the AH stall horn.
You must master the aircraft and it's capabilities, shooting for realistic short ranges, even master the guns and their ability to twitch your plane around a little, throwing your aim.
It's alot less forgiving, I have ruined 109 engines diving on Hurricanes and such just because I feathered my prop a little late. I can tell you the sound and the vibration is an immediate RTB.
I haven't had any problems yet playing the game, apart from it seems to need a super computer to run it with high frame rates. It's a shame I struggle with frame rate because I really do enjoy flying the game.
(Your right though, it dowes make great screenshots, even from my rig.)
