Originality is an urban myth, like "innovation" or "immersion". The only intangible element that matters is fun. I play Mario Sunshine, even though it's just Mario 64 with a water pack, because it's fun. I play Pokemon Diamond, even though it's essentially the same as every other Pokemon game, because it's fun. I play Street Fighter, even though it has no coherent story whatsoever, because it's fun.
Not to be insulting, but you don't get the same kind of
fun out of jumping and kicking around than out of a story-based game, or an interactive story-based game, or an adventure game, or an RTS, etc. Comparing genres that try to do completely different things is what many gamers fail at.
Compare Pokemon Red with Pearl - hmm, the combat is better, the graphics are better, the music is better. Nostalgia aside, it's a better game and more
fun if you look at it that way. Now in a story-based game, for example, improving the twist at the end gradually with each game won't make it any better because
you know there's a twist at the end. It ruins the unexpectedness of the story, and in turn makes it so you get less of the kind of
fun that you normally get out of these types of games.
