Ah, yes, Tiberium Wars and Kane's Wrath. Good games, although they never really topped Red Alert 2 and TibSun. At least the balancing was taken more seriously because EA tried to heavily push C&C3 (and Red Alert 3) as competitive e-sports games (fuck e-sports, btw). They've taken the whole thing too seriously, imho. Which made them a bit less fun. But they weren't so obsessed about balancing and e-sports like Blizzard with StarCraft at least. (I think StarCraft and StarCraft 2 are poorly designed, but that's a discussion for another day).
They also went all out with their live-action cutscenes. It's sad that this was essentially the last hurrah for the Tiberium games, had I known back then, I would've appreciated C&C3 more. It's solidly made, pretty good even in some respects. But I never really liked the direction EA took with the story, world and art design after Tib Sun.
I'd appreciated an even bleaker, more apocalyptic development, where GDI and Nod would've had to really fight against the mutated flora, fauna and maybe the planet itself (Alpha Centauri style, if you will). The Scrin were a mistake and never felt really thought-through and making them playable, while interesting for the multiplayer, pretty much removed all mystery about the Tiberium...
A good 8.0/10.0 in my book.
And before you guys roast me about my statements regarding balancing and multiplayer-focus, you can and should balance, of course! But not at the cost of fun; it should always facilitate it, not remove it. You can have a fairly balanced game but also allow some stupid/weird shit, which Blizzard removed completely for StarCraft 2 (and also later versions of StarCraft 1) because they wanted the matches to be like a professional sport. Look at Age of Empires 2, for example. Pretty balanced game but you can still do a lot of weird shit strategies. Or Red Alert 3 also went a bit more in that direction. Maybe even Red Alert 2, although you can heavily debate whether it is balanced enough. The older C&C games aren't, really. Rocket-based units are essentially OP, since they essentially can hard-counter everything. And the Nod artillery in TibSun is just crazy OP (they remedied that a bit in Firestorm, however).
