Granted Red Alert 1 is a quick cashgrab with minimal effort, but while Tiberian Dawn might not aged most gracefully, it's still not that bad, up until that time you can only compare it to Warcraft 1 and Dune II, and I am sure as shit will pick Tiberian Dawn over them.
Blame SAGE ( Strategy Action Game Engine ), don't know what shithead at EA thought that essentially PC only game engine in 2000s needs to not only be 30 fps locked but also all of its function tied to said FPS lock but they just went with it, I'll still say that Tiberium Wars is still tied as my favorite in the franchise together with RA2, despite dog shit technical decisions.
Yes, it can be enjoyed, hell, I can even say good things about it, unfortunately not a single of these praises are going to make it a good game.
I'd say that the one who suffered from flanderization is the Soviet Union, the main plot of the campaign mimics Yuri's from previous game with few short stroke changes, that and also voice acting which went downhill into pure farcical clown fair, and both soviets and empire end up being butt of the joke anyway.
