Players very widely disagree with me about what's hard and what's easy. and in a way, 'I won, but it was a fight' is the best compliment a game can receive.
Then in my early teens, when the home computer bubble was blowing, I had one of the first, an Acorn Atom, and used to write primitive adventures on that.
If pushed, though, I'd say that the next stage will be reached when it it's no longer true that about 75% of the best games were written in 1980's on the way to that.
