DFXOpsy, frankly, Aces High has stayed the same way for a very long time.
Just compare some of the latest flight sim games around - HTC has been on the side of the low-end users for a considerable amount of time. Even by the standards of non-boxed, MMOG combat flight sims, AH is starting to lag behind.
It's about time for a new AH: new users with more powerful systems are always more interested in the visual qualities than the game itself - it's how things are.
