I'm posting this because I don't know which one I like better.

I'm an astronomy nut but I also love aviation. However I am neither an astronaut or a pilot. *weird*

I enjoy Microsoft's Flight Sim series but have you ever heard of Orbiter, the closed source freeware space simulation. It's pretty cool, tons of addons for realistic or futuristic spaceflight. It's European so it's all metric though.

Space Simulators . . . . . . . . .

Same here,

i do love both also and heard from both. Especially Orbiter is a neet simulator.
Comparing atmospheric flight with space flight is imo almost impossible, 'cause
they are subject to different behavior. But still both is very interesting and does
make lots of fun

Edit: the more realistic, the more fun it is, because it takes a while to learn how
to fly them, imo spacesim more than flightsim ^^

Thanks for the feedback guys. I would agree with both of you, Space Simulation is so much more in depth, so much going on to achieve a good orbit.
