No, that is truth. Right out of the box you started doing what the parent eluded to, i.e., interpreting the statement. In the hypothetical study, more cows from one group died. How is that a "theory"?
No, not "certified to EAL7", it is "designed to be certified at EAL7". Vendor assertion vs 3rd party evaluation.
The difference is fidelity. Simulators strive for real-world emulation. Educational sim games abstract away a lot of details and will have lower fidelity. The purpose is often to get familiar with basic cause/effect within an environment in which the player can win or lose and experience a variety of situations. Sim games also tend to contrive the virtual world to present conflict and entertainment. I build CyberCIEGE, which most definitely is NOT a real-world simulation of network security. However it is a constructive management simulation that confronts players with choices that lead to learning. And, for at least some students, it is fun.
