Why I already have those, well kind of. :D I have C&C Tiberium Sun, Tiberium Dawn, RA 1 & 2, Renegade, and now C&C 3 complete

Frankly I already owned the whole series through The First Decade + Steam (and I still have the German original DOS release of Tiberian Dawn lying around somewhere). I *really* wanted to have digital versions of the whole series in one place, though, as I was tired of having to use the TFD disc and go through its awful installation process every time (not to mention community patches that go on top of it). And during Origin's Autumn Sale it was really a steal. The series is as brilliant as it is stupid - gotta love it.

Fun fact btw: In the German release all soldiers were robots and would bleed black oil when they die. They would actually be referred to as "androids" or "robots" in the cutscenes and briefings. In Generals the character icons even had hilarious cyborg details applied to them and suicide bombers were replaced by cars. >.<
