Do you know if it's any good? I have never heard about it actually.

It's lacking a good deal of polish, but it's a good effort. It's more or less a direct clone of Frontier/FE, practically to a fault, though sadly without any of the original ships due to copyright restrictions. Surprised oolite hasn't had similar problems.

There's also a commercial space sim based on it in development called Paragon which might be worth keeping an eye on: http://www.paragongame.com/
