The constant references to earlier Tiberian games that C&C3 made. One example is that the Nod Emissary will display a holographic image of an FMV sequence from Tiberian Sun.
This is a deployed Nod Emissary in C&C3: Tiberium Wars. Notice the holographic image. I know it's a bit hard to see it in this picture but in-game you'll really notice it.
This picture is from an FMV sequence in Tiberian Sun. This is the Emissary's holographic image. You can view the FMV sequence in its entirety below.
They also stuck so many other references to earlier Tiberian series games in there.
The above are a few old vehicles from Tiberian Sun and Tiberian Dawn, recreated exactly as they looked.
There's so many other references EA made to earlier Tiberian series games in Tiberium Wars and Kane's Wrath but I'll leave it to you guys to see them for yourself.
