Just had the demo running, no special things I did, just saw the start, and transiting to orbit, from within and external view, VC with plenty of MFDs in sight) and 2D panel views - with maxed details and desktop resolution 1280x1024, frames always were a blast on my old system (P4 3GHz, 2 GB RAM, AGP 7800GT, winXP).
Plenty of switches. Switches everyhwere. This really is a switchsimulator. After playing this you really know what a switch is, how it is handled, and what it does (flipping to the next position).
I consider to buy it once I figured out how their licensing system works. If reinstallation always needs a new licence from their website, it is a no-go for me. when I pay for it, I demand full control over the ability to reinstall it on my system as often as I want without depending on external services, companies still existing, or internet access.
