That's a great list of cartoons.
Space Ghost was great! Then they brought it back as a talk show which I watched late night as a teen. Funny stuff! They also rebooted Wacky Races a few years ago but I haven't watched it yet.
I saw the Wacky Races reboot recently. It was pretty good, but I still prefer the original. The biggest difference is the cast has been whittled down to five racers: Dick Dastardly and Muttley, Penelope Pitstop, Peter Perfect, the Gruesome Twosome, and some little geek named I.Q. Igley, probably named after one of the show's former producers Bob Quigley. There's also an on-screen commentator instead of an off-screen announcer.
