Agreed. If they can make the gameplay really good to go along with it, you have a winning game. I mean, look at Halo.
Well... personaly I've always wanted a storyline in AC that explained how the duece each side in the game's conflict have the most advanced aircraft at their disposal from all the various first-world nations/militaries/governments. But it might just be me.
Please don't turn this into a 360/PS3 thread...
I love the AC series. Air Combat was my first game. I rented AC2 enough times to buy the video store. It makes me cry how badly the West got shafted by AC3 (seriously, in Japan it ought to rival the Final Fantasy games besides the fact that there's only one AC3). AC4 has the best soundtrack I've ever heard by far. AC5 added great game elements and had a pretty decent story to go along with the usual "Oh $!^*, here come the ____, lets win the war single handedly!" plotline. Ace Combat X is an interesting little sideline, good for sitting in doctors offices or on busses. AC0 is where it kinda started to grind and a little more of the uber-endboss schmaultz started piling up. AC6 has WONDERFUL game aspects with the Allied Support system (though they nerfed the wingman support), but it seriously goes over the top in the cheesy aspect. I do love those three tards in the tank, though. That had me laughing for quite a while.
I didn't like AC4's storyline but I enjoyed the gameplay and the music too. I remember that the music for the game at the time was one of the few games on PS2 that had well-matched music for what you were doing in the game, which probabley made the gameplay twice as enjoyable for me at times.
AC6 is my current and longstanding favorite on my current console (XBox, the other games come along, but they go

). I lost my old profile I had with it in October last year, so atm I have the
pleasure of beating the game on super-hard all over again... thankfuly this topic just might convince me to do that this weekend. I play it online the most of any of my XBox games too, and just last last week I unlocked the decorated ace achievement thingy again online (that's not actually a real XBox achievement

).
The first time I saw the storyline and those tankers I swore they were going to pirate the golden king (

), but that quickly got squashed for the best and made me laugh for a while about me thinking they were going to pirate it. And speaking of cheese, my nickname for the main woman character in the storyline is "the woman who needs some more cheese with her whine".
Glad there are a lot of other AC-dweebs and dweebets here. Anyone who still plays AC6 on their XBox feel free to add me (Playr4). I mostly play it very late in the evenings though.
