MS Flight simulator is history. It was taken over by Lockheed Martin, and is promoted as a training tool.
As for the 777: This is a picture of a MS Flight simulator addon from PMDG. It is not just eye candy, it has a programmable FMC, nearly all switches work as they do in a real cockpit. TCAS works. You can simulate failures. You can autoland. All APFD modes work. Autobrakes, autospoilers, cockpit lights. LNAV/VNAV. Radios. Transponder. All displays work. You can download realtime weather. Download nav database which is just the same as the one you got in the real aircraft. You can set it up as a virtual cockpit with the right equipment. Look around the cockpit by turning your head.
Ii is not a toy, it is usable as a training tool on your home PC at the fraction of the cost of a real simulator.
