#18 - Command & Conquer: Tiberian Sun Firestorm (PC)
I've put my entry as the expansion pack, 'Firestorm', as that is by far and a way the version of the game that I spent the most time with, but I suppose I'm also including the original game in this entry as well.
Tiberian Sun followed on from the first RTS I ever played, the original Command & Conquer. We got the enjoyable Red Alert in between, but that never quite caught my interest in the same way that the tiberium universe did. So dipping back into it with familiar units but a whole host of new stuff, new tactics, new bases and a fantastic new plotline was an absolute blast.
Speaking of plot, despite C&C's bashing it gets for live action cutscenes and melodramatic plot, Tiberian Sun actually told a really interesting story. Firestorm improved on it even more - fighting against CABAL genuinely terrified me when I played this game as an 11 year old. Aside from that, the tiberium universe was more atmospheric than ever with new types being discovered; men turning into mutants; remnants of the last game left scattered around the battlefiend and so on. Mix this in with some of the most solid and enjoyable RTS tactics I've ever played and you've got a real winner of a game.
