Indeed, EGT, CHT, Manifold Pressure and RPM were all available on the real Lockheed Super Constellation as well as the pre-WWII Lockheed Constellation. They also have a gauge labelled 'Brake Mean Engine Pressure', which also reports a super useful piece of information for working out the ideal mixture.
To be noted, they also had a flight engineer on board who was tasked to monitor all of those indications, and to operate the engines and aircraft system based on the indications.
No such prudent measures are taken with my flight simulator. But I'm somewhat proud of being able to manage as captain, first officer, radio man, navigator and flight engineer simultaneously. Crash rate is down to one in tens of flights as well ;)
