Simulation???? According to Amazon.com SHV is an "Adventure" game not a simulator Don't believe me, see here:

Look under the "Product Details." Quite frankly I agree with them, SHV is subsim "Lite". Hopefully, a supermod will raise it to GWX, but I have my doubts.
Now, would MS Flight Simulator have become as popular as it has if you could walk all around an airplane, but the only airplane you had to fly was a Boeing 747? Steel Beasts is an outstanding tank simulator, yet there is no interaction with other crewmembers, the same can be said for Dangerous Waters and other Sonalyst submarine titles.
I enjoy a real simulation, that's why I've stayed with SHIII + GWX
