Sounds great but 49 minutes 20 seconds to download it. It will have to wait till our town has broadband. I have stuck it in favourites so I don't lose the address.
Yes it's very nice if you get it installed properly and you have a well supported 3D accelerated video card. There are extras to download like some very detailed (HUGE) maps for some of the planets, esp. ours; lots of small objects too (asteroids spacecraft/junk...). Flying around in the solar system is a lot of fun!
