An FNPT2 sim is a PC and a projector plugged into a cockpit mock up of a particular or generic aircraft. It may strive to fairly accurately model how a particular aircraft behaves - but then it may not.
It is in NO WAY an actual (in this case) B737 NG Sim. It merely looks a bit like one and might behave a bit like one. A real Simulator costs well over a million pounds. An FNPT2 - well lets say £100k would get you a nice one and a building to put it in.
