They ripped out some of the most fun parts, and the initial release of - for example - Tiberium Wars was a huge buggy piece of shit. I can't count how many times the thing de-synced and crashed during online play within the first 6 months of patch-cycles, not to mention the bugs that often left single-player missions somehow unfinishable.
You DO mean Tiberium Twilight (CnC4) don't you? Tiberium Wars (CnC3) came out in '97.
You scratch my tape, and I'll scratch yours.
