For anyone who can't wait until next year for ELITE: Dangerous i recommend the free and open source Oolite, especially with all the easy to install add-on expansions available on the Wiki it's a great hommage to the original (1980's) Elite (but with better graphics). Of course it's no where near as good as ELITE (4): Dangerous is going to be but until then it's pure snake opiate in our veins.
