I have fond memories of loads of shows and I also bought a few on dvd to rewatch. Teenage Mutant Ninja Turtles was my favourite for a long time, for a while there was an episode on every day at the perfect time before I had to leave for school. Another big favourite was The Visionaries. A lot of people write this off as being made purely to sell toys. Maybe it was, I don't care it was the best. And it still holds up. Amazing intro too. I also loved Dogtanian and bought it too. Agree on Willy Fog and Mysterious Cities of gold too although I remember little about Cities of gold other than the theme tune. I was also a big fan of Mask but I saw an episode if it a few years back and it was actually terrible.
