Tiberium Twilight hands down if it was resurrected by Petroglyph. The universe wouldn't be in shambles if wasn't for EA screwing up the story line and unit structure of the previous games with C&C3. I really enjoyed C&C3 as a game in itself, it was very well built and a lot of fun but if you look at it compared to the other games in the series, you get this... "wtf happened to this and that?" feeling.
Renegade 2 would have been an awesome extension to the Renegade multiplayer but the campaign would probably blow like the first one. I only played Renegade online, I never got past the third mission in the campaign. It was sooooo boring, linear, cliched and uninteresting. I would love to see EA Dice make a online muliplayer game based on Command and Conquer, that would be sick.
Tiberium failed in art design, while it had some interesting ideas and gameplay mechanics; the whole game looked bland. I'm glad they canceled it. It would have further tarnished the C&C Universe.
