I've said it once, I'll say it again. Aces HIGH is ALL ABOUT FLYING. Vehicles are not here to be a sub-game unto themselves, but merely to add another dimension and flavor to the immersion factor and overall gaming experience. If you are flying Aces HIGH expecting a massively multi-player tank sub-game that is on par with the principle flying component you need to work on your reading comprehension skills.
As far as bugs go. A massively multi-player game such as Aces High is constantly evolving, adapting, expanding and changing. These types of games are always in a state of dynamic flux. They are never completely free of bugs. The developers will kill the show-stopping bugs quickly, but in a game this complex, running on an almost infinite variety of platforms, bugs are just a fact of life. Leaving AH in search of the perfect, bug-less game that offers anything even close to the entertainment value AH does for the money is akin to searching for the Holy Grail...Good Luck
