Technically its everything that the original two incarnations of MSTS 2 were supposed to be, however it comes with a small amount of bundled content/routes and what addons are out there may need patching to support the updated game engine.
North East Corridor was released for Railworks 2 but they did not patch it until a short time after Railworks 3 released.
You have visible light beams and shadows through the cab windows and the trains roll about, the sound especally for the GEs is good. A reasonable system is required.
It has been a headline game on STEAM since release so its geting exposure to non gunzel community and occasionaly theres discounting on it, must have for gunzels maybe, but a bit oversold by the developer though.
Very fun to play with the updated physics but unless you have many addons and especially updated addons your going to get bored quick
