Yes, very true. There's also:
Castle of Illusion which I really enjoyed when I was young, and they happen to be remaking.
The Toejam and Earl games for the Mega Drive (Genesis) were quite fun! I'm not sure which one I enjoy more. I just saw that there was a third one, but it doesn't really look good - especially not compared to the first and second!
Anyone ever play Alfred Chicken for Super Nintendo? That was pretty cool! At least from what I can remember.
A fairly dated PC adventure game, but it was quite good back then! It's called Atlantis: The Lost Tales.
