I used to love the C+C series. Dune was my intro into RTS games. Something about sicking dogs on soldiers in Red Alert had me. The first was good, but red alert was amazing to me. I'd have to say that the Command and Conquer series is probably what got me into the Total War franchise. I do not play C+C anymore, and haven't for quite a few years. I think C+C Tiberian Sun was the last one of the series I played. It didn't have the same appeal the first 3 did.
