Ace Combat on Ace (not ace of aces) in several levels is extremely difficult, and will require many restarts, but at least it can be from the last saved, but if you have not the right amount of ammo from that point, it’s futile even considering it, and you should go back and start again.

Especially the level Weapons Of Mass Destruction. A time sequence low-level run through a very difficult valley/raven with several locations you have to wipe out before moving on, in order to destroy the train carrying the WMD before it enters the tunnel. Not easy at all on the top difficulty levels. Then there’s the one where you have to eliminate the stationary Rail Gun, THEN fly inside it, (through the barrell) and then hit the core generator before you are shot down – at SPEED.

Takes several attempts before you realise the best way to do it.

its all fine and dandy to have a game hard, in fact i like hard games BUT easy difficulty is called easy for a reason.
ITS SUPPOSE TO BE EASY!
if they want the game so bloody hard thats fine but have that as the hard difficulty setting NOT THE EASY SETTING!

all games should have minimum 4 difficulty settings.
1 easy, beginner you have never played a video game in your life.
2 medium, you have played a few games and are half experienced.
3 hard , you live and breath games, you have battled through countless experiences laughing at the challenges.
4 extreme (or whatever you want to call it) this is reserved for the best of the best only gods play this and live to tell the tale.

a example of a game with perfect difficulty settings would be killzone 2.
easy is easy, medium is medium, hard is a little easy for my liking but meh, and elite jesus christ its the hardest game ive played harder than crushing on uncharted.
or even DMC4 its to easy on easy but bump it up from there and its challenging.
play it on son of sparda or dante must die now thats bloody hard.
