Frontier Developments has just released the first beta build of Elite: Dangerous, the space-sim that has been available via early access for some months. The alpha version of the game was fairly expensive (it cost £100), and that price has come down to £50, which is still not cheap, but does at least represent better value. If you're interested you can find out more or buy the beta here. Alternatively you can wait for the final version of the game, which is expected to retail at around £35.
