Realism, whats missing?

[Buren]

I don't think so, it isn't a procedural sim.

I think the best analogy for a "Can I learn to do stuff from virtuality" is when you only, suppose, "learn" how to play a piano by playing around with a "virtual piano" app for a smartphone/tablet then you find yourself in front of a real piano -- you realize it's similar, but there's a lot more to it, which you can't learn only by the limited scope of virtual emulation.
