No, it'll still be shit.
I guess I lost this debate the minute I stepped into it.
I wouldn't go as far as call it Shit, Assault Horizon was kind of a "Brave Experiment". I actually respect Project Aces for trying something different because as much as we don't want to believe it, the series was starting to get maybe a tad stale. Changes have been somewhat minimum over the last few titles, in particular from AC04 onwards IMHO. I still love them, but then I'm biased because I'm a big fan of the series.
I also fully understand why PA decided to go for a more accessible approach to the gameplay. If the regular installments are not bringing in the profits desired, then the only choices are to change up the formula or but the series to bed. I myself don't want the latter so they went with a change up. Of course whenever you change, you have to accept that things mayu not go according to plan and so despite an upsurge in sales, it wasn't enough to reach the numbers they were probably hoping for, hence they took feedback and implemented it into Ace Combat Infinity (I have my own set of problems with that game but thats another topic for another day in another sub-forum).
All in all, Assault Horizon probably will remain the Dark Horse / Black Sheep of the series (though who here has played Ace Combat Advance?) but I still see it as a unique experiment. I wouldn't rank it high in my order of preference in the series (too much emphasis on multiplayer is actually the big killer for me) but I still get a kick out of replaying it every now and again.
