Endless Sky is a free/open source game in the spirit of Escape Velocity, I recommend checking it out if you're a fan of the Escape Velocity series.

Also there's an Escape Velocity remake called Cosmic Frontier which has been in the works for many years which I recall hearing had the original developers blessing to use their assets.

Oh man I loved those games and I never hear anyone talk about them anymore! They were so fun. I found out about them because someone installed the shareware version of the original on one of the Apple computers at my elementary school. I remember when EV: Nova came out and the ships finally had engine glow it was a HUGE deal.
