I peeped over Trent's shoulder when he was playing G-LOC a while ago, and it looked a bit like Afterburner. So the wheel has come full circle (whatever that means).
You fly a plane (seen from behind) which continually pours out little black bullets. You've got to hit the planes that come racing towards you, while jinking, jerking and jumble-saleing all over the sky.
The problem is that the plane isn't easy to control. It continually fires out bullets, so there's no danger of running out, and all you need to do is try and blast off missile after missile. Not amazing interactive action, I think you'll agree.
You'd do better to wait until G-LOC comes down to a realistic and affordable price, I reckon. Afterburner just doesn't spread the marmalade.
