List of the 100+ most influential arcade shmups

[Ed Oscuro]

Yeah I guess that was mentioned already.

Did you know that Hill Street Blues was more influential than Miami Vice? *slaps knee*

Maybe Konami's lawyers were lazier, or exhausted from dealing with so many Space Invaders
clones to have little time for small fry...

Actually it was Taito.

You're right, of course. I've edited the entry, thanks for the correction.
By the way, updates are slow, because we've been traveling overseas.
I hope to continue the project at some point in the fall...

Is this still going/accepting new entries?

Been dicking around on MAME and I have A Few Suggestions:

Cosmic Avenger (Universal, 1981). From what I understand, this is the first single-direction horizontal shooter, beating out Scramble and the like (and it has fancier graphics too). Doesn't seem right to leave it off the list.

Sheriff (Nintendo, 1979). If not the first twin stick shooter, the dial system certainly made it mechanically similar - probably making it the first game of its kind that I know of. I had no idea it employed that feature until just a few hours ago - I guess I always just dismissed it as a knock-off of space invaders that had the invaders circling you instead of just at the top of the screen. Got to hand it to Miyamoto, people say he gets too much credit but stuff like this suggests he might not get enough.

Sky Raider (Atari, 1978). Really just a shooting gallery - no way to die, just blow away as many targets as you can before the timer runs out - but there's a (very impressive) vertically scrolling backdrop - not quite the first one ever, but not far off. Probably wouldn't qualify as a game if not for the ability to slow down and speed up the scrolling, which adds a small decision component on top of the skill component.

Astro Fighter (Data East, 1979) Collaboration between DE and Sega. First vertically scrolling shooter that was actually a game and not a shooting gallery - IF you consider 'moving stars' scrolling. Data East's first game! Seems weird to have Astro Blaster on the list but not this, as it is sort of Astro Blaster's pappy.

Phantom II (Midway, 1979). Pretty sure this is the first vertically scrolling shooter where you control a ship and the backdrop is something more than just stars.

Thanks for the suggestions. New candidates for the list and comments
are always welcome. The project is only semi-active at the moment, but
I hope to get back into it at some point. I'll add a few more shmups I
missed based on suggestions, and then probably prune the list down to
100 when it's done (whenever that is).

Another one:

Rougien (Sanritsu Denki, 1982): Split into several different sections, a standard Space Invaders-style shooting gallery, a scrolling section where you fly over a huge battleship with turrets firing rockets at you (is this the first instance of that? Kind of a genre staple), then a 3D tunnel section with you rocketing through winding passages that make up the interior of the battleship. Ends with a boss fight against a weird critter that is either a mouth or an eye - too hard to tell.
