Well there is 2 things I would like to say, the first being that realism =
is great, but keep in mind real-life is not always that fun.=20

Okey back to the point, I know exacly what steve is saying, I don't play =
space sims for that reason. They always feel slow and borring, nothing =
to compare your speed with. If your in a bus doing 50mps and you throw =
an apple in the air does the apple look like its moving 50mps. If you =
are on the bus no.=20
There has to be something to compare with, I had the chance to fly a =
little airplane and it felt really slow at 4000ft, but only to find out =
that we where moving at 200mps, but if I was doing that speed in my car, =
I can garranty that my passiongers would be crying.=20

There is only one game that I can think of off-hand that give you an =
idea that your moving fast, and thats star-wars (the new nes64 racing =
game), there are lots of queues for your brain, the ground is blurrie =
cause it moving so fast and everyting around you is moving fast. Give =
you that !!!WOW!!! i am moving feeling. Or need for speed, gives you a =
good idea about it too.
