Fuck PC and Fuck Digital, you can't make a day job out selling 2000 games at $10 (or less) each when a game takes a handful of people over a year to make. You can't put food on the table that way, and it's folly to try.
if you're trying to make a living making something that's as dead as shmups, you're dumb as hell (note: they're not making money off shmups but overpriced "retro" stuff)
doujin is the future and they can take all the time they want for a single game
Arcades are obsolete, and have been for years.
releasing their mediocre games on something as outdated as pcbs is a total joke
So are physical releases
honestly you're better off just making shmups in game maker
it's easy, works just fine and you can instead focus on making the gameplay suck less
except then you can't sell it for $400
