Oh hell no. Ace Combat controls are so much different and laid out so much better on the controller it's not even funny. Battlefield really needs to look at Ace controls and, honestly, just outright copy them. Everything is so perfectly laid out it's like a dream. All the weapons are on easily accessed buttons, throttle and brake are triggers (R2 and L2), Yaw is L1 and R1, joysticks are mapped perfectly for flight, and oh so much more.
Assault Horizon's dogfight mode was annoying as hell and it was the only way to actually take out most fighters with one hit. Honestly the game wasn't all that bad it just had a shitty plot with a very shitty setting (never, ever place an Ace Combat game in the real world again Bandai Namco. It just doesn't work). I finished it and outside of the final duel with the "Shark" it was all pretty lackluster.
Considering how well co-op did for 6 and for Assault Horizon I'm pretty sure we'll see it included in 7. All I know is I seriously can't wait, I just re-watched the trailer and I'm shaking with withdrawal. I might have to dig out the PS2 and play me some Ace Combat 4, 5 and Zero this weekend (yes they are all easily beatable in a weekend and I have beaten every single one on Ace of Aces/Hard mode (that's how much I love these games)).
