Marsport! I had forgotten that one, a great game.My memory of the Hobbit was "you are in a tunnel..." and incredibly long loading times.
Amusingly, my son in law just got Bejing Olympics on PSP3 and it was a prettier version of Daley Thompson's frantic joystick wiggling all those years ago!
Ahh Daley Thompson on the spectrum's rubber keys....
And the hobbit, great fun the old interactive fiction games, personal favourite
"you wake up. The room is spinning very gently round your head. Or at least it would be if you could see it which you can't.
It is pitch black. "
Describes most mornings for me!
