I was meandering the Google-ma-bob, and I came across this FlyingGuns. I downloaded it (click Download, click FlyingGuns 0.3b3, then choose your OS), and gave it a play. The flight characteristics are strikingly similar to CS (PC) and pretty much feels like an Instant Action Dog Fighting a Squadron mission, only the planes seem to go after eachother with no real team-orientation (whether its German, French, or British). But it's a great way to waste time if you just want to shoot someone down.
You can fly either with the mouse by moving the cross around the screen (up and down is inverted), but it recognized my joystick after I moved the cross off the screen. Left mouse button or trigger shoots the gun, all (4) aircraft seem to have the same gun no matter what, so all craft are equally matched. It also looks to have multiplayer support, but I have yet to see if it works. Googling it seemed to get me no where, which explains the name of this post, and I can't find any mods or forums concerning it, which is why I posted it here, so that it may be ogled over by people who respect this sort of thing.
Anyways, you need a recent version of Java to play it (doesn't hurt to be new), doesn't need to be installed (just placed somewhere familiar), and barely takes up more than 4MB.
