Anyone on this site have a career related to video games or media studies and teach things like that? I think there needs to be something like that for video games due to their rapid evolution. This little gem (I haven't played, I probably added it to this database though since i'm the only one who has listed it) was distributed originally at Comiket 73. It's gone through several evolutions and stands out to me because it is one of the more rare ones that doesn't rely on just one subgenre but features many japanese shooting (STG) sub-genres. It has vertical shooting, horizontal shooting, rail shooting. There are boss rush versions and I think another version (possibly score attack, but can't recall)

I find this fascinating. There are likely millions of scrolling shooters by now due to their age and origin and low time/budget/skill of producing them. I cannot help after playing S&P (which went a similar route with the multiple subgenre thing) if there has been a game that deliberately tries to do all these things, PLUS other things such as caravan shooting segments, fixed shooting segments (space invaders) command shooting (missile command) scene, run and gun/Platform shooting, light gun segments, AND includes other shooting sub-genres (Top down such as multi-directional shooting and twin stick shooting... Behind the back and third person and FPS segments. It would be especially neat if it made a clear distinction between them all in such a way because most people don't know the difference, but manages to make it in such a way that they also feel like a smooth transition

Kind of like an evoland... but for the colloquial 'shooting/shooter' genre. It would be interesting to see a game try to articulate and break down all of these things into a way that as you play it you can process it. Or it could do its own thing. I think this is a really good idea. It's probably already been done, it seems a likely Comiket release even. I'll just have to keep playing until I discover "SHOOTER GAME"
