I downloaded the demo from Xbox Live a couple of days ago and I'm not so sure...
From what I've read Birds of Prey is supposed to be the first "proper" flight sim on a console, so I had high hopes. The demo features two missions - one flying a Spitfire intercepting a large He 111 raid over Dover during the Battle of Britain, and the other flying a P-51D on ground attack mission during the Battle of the Bulge.
First of all you have to complete the missions in "arcade" mode first before you can unlock "Realistic" and "Simulation" modes. The arcade mode is ridiculuously easy - in the Spitfire mission I shot down 23 Heinkels in a matter of minutes. When you engage WEP (War Emergency Power) on the P-51D the thing accelerates like a Eurofighter! The other thing I noticed was the BoB Spitfire in the game is a MkV. Anyway, I persevered and immediately re-flew the missions in simulation mode, and it was still too easy - the Heinkels all fell too easily to machine gun fire, I could still hear overly dramatic German radio calls (maybe I had the electronic warfare version of the Spit?) and the whole experience was still too much "arcade" for my taste. The missions themselves are also too arcade - shoot down eight Heinkels, and then three Stukas.... blow up these eight artillery pieces, then these six Tigers, and finally two trains.
I've played the IL-2 series since it's original release all those years ago, and I've owned every incarnation - IL-2, Forgotten Battles, Ace Expansion, Pacific Fighters, and 1946 - and the new console version does not stay faithful to the PC version. It's kind of disappointing seeing as the IL-2 series was always well known for it's attention to historical details and accuracy.
I was probably expecting too much from this... it's been dumbed down and concessions made for gameplay when compared to the PC version. It's fun for a while, but ultimately left me (as an avid flight simulation fan for many years) disappointed. On the plus side though, the graphics are very nice, and the terrain is the best I have ever seen in a flight simulation, albeit at the cost of visual range, which is extremely limited to keep the framerate high.
Anyone here who still plays the PC version of IL-2 I would suggest you check out the new mods for this sim if you haven't already done so.... for many years the IL-2 series was not mod-friendly, the developers locking away the aircraft, scenery, etc in encrypted files. Someone managed to break the encryption a while back and there has been some awesome mods made for the sim. There are now loads of new flyable aircraft.... Spitfire MkI (FINALLY!), Spit VIII, Spit XII, Spit XIV, Typhoon I, Hurri IID to name just a few. There are also lots of new maps including a proper Channel map so we can now fly BoB missions in the proper setting at last. As I write this I am just downloading a new campaign where you fly a Mossie from Malta on night intruder missions over Sicily
