My list:
C&C Red Alert 1, my very first game for PS 1, together with G-Police^^
C&C Tiberium Dawn, It was my favourite C&C back then...
C&C Generals, (My now favourite game, but not cuz of its story... I think it was the music )
C&C Red Alert 2 + Yuri's Revenge, story was fine for me... Yuris units we're also fun
C&C Generals Zero Hour, oh well... Just like Generals, boring story, awesome game and music
C&C Tiberian Sun, At first, I loved that game cuz of its cutscenes (Slavik is da man!).. After a while i stoped playing it... At least i completed the game... Never played the Add on though.
C&C Tiberium Wars, The cutscenes in my opinion we're great (although they cant be a match for the cutscenes in tiberium sun, except that they are aviable in HD ), the game was better than TS, except when it becomes to atmospere (I mean, hey, Ion lightnings and stuff? I missed them in TW 3) . One of my favourite games...
C&C Red Alert 3, oh well... I dont like it... story isnt that good and the units... oh well... i dont think i would command them... I never completed it (story wise).
C&C Tiberium Gaylight*: Whats that?!
*I know this was the name that Westwood wanted to give their next C&C.... but wayne
I hope, i didnt hurt anyones feelings
