Man, I miss all those Ambrosia Software games (Apieron, Barrack, Escape Velocity, etc). I love how many are pre-loaded there, but the few I tested all seem broken.
Also, you can still get EV Nova on a Mac as far as I'm aware. The price hasn't decreased in about 20 years though.
There's also an open-source clone, Endless Sky [0], and a recently-Kickstarted project to re-create EV Override for modern systems, Cosmic Frontier: Override [1].
