I've been messing around with the beta, and I think it looks great. It's a real step up from Aces High 2, and you guys are doing great work.
Unfortunately, just like in AH2, the game comes close to giving full support for 3D tech, but it's still not quite there. I think that with 3D goggles like the Oculus Rift and the Vive coming out soon, 3D support is more important than ever.
The beta doesn't have much wrong with in that regard, but the problems really mess up the whole experience.
The main problem in AH2 and the beta is that the virtual gunsight is not out on the horizon; it's up against your face. In 2D, it looks like it's out there, but it's not. So, in 3D, when you're trying to aim at something way out in front of your plane, you get two copies of the gunsight on either side of your nose, and it's impossible to aim (just like if you held your finger up in front of your face and got two see through copies on either side of where you're looking). If you could somehow push the 2D plane of the gunsight out to the horizon, it seems like it'd fix the whole problem.
The other big problem I saw in AH2 (but not in the beta since I haven't actually seen another plane yet) is that the badguy (plane, tank, whatever) is way out in the distance, but his icon is again right up against your face. Also, it's butted right up against the enemy plane so it's hard to focus on either the plane or the icon.
Also, In the beta, when you pull up the clipboard, it sits correctly physically in front of you, but the mouse pointer is sitting way behind it, so it's really hard to click on anything on the clipboard since you have two copies of the pointer. Strangely, when you modify your keyboard control mapping, the interface and the mouse sit on the same plane correctly.
Pretty much all of the physical stuff in the game looks amazing using my 3D glasses; it's just some of the 2D stuff like the gunsights and the pointer that really mess it all up.
Like I said, though, the new beta is looking fantastic! Keep up the good work!
