Spring RTS Engine

wings 2 a pretty cool "gravity shooter" (think like lander, or asteroids in an environment with gravity)

Lots of game modes, huge weapon selection. Not actually sure of the lincensing, but there are loonix versions and stuff, its free at least

Yeah, go buy soldat, you get custom colored jet fire... great deal

Haha wings :')

If you're looking for oldschool splitscreen fun like wings 1.4, try triplane turmoil. Not exactly a cave flyer, but close.
