what are some good simulation games, is ther any airplane ones were you have to land the plane, whats the best sim games ??
Look into the X-Plane series. In general for simulators, get Enviro-Bear 2010, a pretty realistic and high-quality sim.
I second that. Enviro-Bear 2010 is brimming with quality and realism like no other game. I mean, when you play it, you actually feel like you are a bear with one paw driving a car trying to collect fish and berries. Pure awesomeness.
If you're looking for an airplane sim, go with x plane. But, if youre looking for a space shuttle sim, check out F-Sim Space shutttle. I just found it and it's much better than Laminar's shuttle sim.
