The Shooting
In a sense, the interaction in a shooter is about the most basic interaction available in the medium. You reach out and touch your environment by sending out a “ping”; a probe. As you mention, the shooter is the original videogame — starting with SpaceWar. Even Pong operates on a similar principle, really. It’s just… backwards, kind of, in that the “bullet” is coming toward you, and you’re trying to catch it. (I don’t quite like this model as much.)
All through the medium, shooting more or less equates to exploration. In Metroid, you test the walls, and get a feeling for your environment, by shooting at them and it. In Asteroids and Centipede, your shooting shapes the very gameworld.
It was something of a revolutionary leap to switch away from this mechanic in Pac-Man and Donkey Kong and Super Mario Bros. — that whole thread that I was mumbling about before. In that model, you’re no longer pecking at the environment from afar but personally running around and punching and gobbling and jumping through it. Sort of interesting to tie this into what I was saying earlier. Not sure how it all goes together.

Mizuguchi went back to a rail shooter for Rez for a reason: he wanted a clean slate; to strip away all of the junk we have piled on top of the medium for the last few decades, and make the most basic videogame he could, that would still be palatable to a contemporary audience. There’s nothing more basic than a shooter. This is ground one, for videogames. Everything else is built on, or exists in rebellion against, this mechanic. Mizuguchi then tried to find just how much he could express with this mechanism — to show, in part, that it’s not the game system which necessarily drives a game, on an artisic, on an emotional level. Also, just to show how much can be said with how little — and thereby to ask why we have come to tend to express so little with so much.
This is why I like Rez — just the whole way it disassembles our whole notion of the videogame, and shows how it might be used more well than it has been.
I’m really curious what his next step might be.
Parts of the above, combined with parts of what I said about Gradius V
