Back in 1987 when I was the tender age of 5, (aaaaah!) i was introduced to a tv show that was to remain fixed in my head for the next 20 years and will probably remain there for many years to come.
The tv show was called Knightmare and was something of a innovation for its time.
Back then, most kids game shows were slimy to say the least (all the games had that interesting idea that the slimier the game the more the kids would like it) but this took it to a whole new level!
First it was done using computer graphics, which created entire rooms and filled them with the most unusual creatures (walking skeletons being a favourite of the designers) and then they added real life actors in order to create a realistic slant to the proceedings
Second the main character was a young child around 12 though sometimes older who was for obvious reasons blindfolded using an unusual helmet
There were three advisers, usually one was designated the spellcaster, another was the navigator and the third usually advised them on what to say to the various characters that the dungeoneer would meet on their quest.
I should point out that the dungeoneer didn't actually die! if they failed they were simply showed at the end in one piece and sent off with a scroll for their achievements!
