I don't like the look of those aircraft. I don't know why, but they just look bad to me. I want to play a game, not train for the USAF. I remember two things very clearly in Ace Combat 4 (not 3). One was flying threw a canyon at insane speeds speeds (I would clime to the top of the map then nose dive into the canyon with engines to full pull up at the last minute then fly threw at full speed), and the other was shooting down Yellow Squadron with nothing but machine guns on the second hardest difficulty level (I got bored before I unlocked the hardest). Would that ever happen? No, but I'd take that over looking at ugly WW2 era planes any day.
[edit] By the way, what would you call something like Ace Combat? I can understand completely why you wouldn't want to call it a simulator, but I don't know of a better term.
