I play shmups to have fun and shoot shit.
If I wanted to do science, I'd do something useful. Like frog autopsy.
If a shmup beats me, it's because I'm not skilled enough. Because I can't control rank. Because I'm not good enough for the second loop. Because I did stupid mistakes. Because I can't score for extends or chain medals for them.
Not because I'm refusing to learn two pages of theory for of one attack.
Shmups are supposed to be fun. This isn't fun.
Shmups are supposed to be easy to pick up, simple to learn but hard to master.
If you just pick up UFO lunatic to shoot stuff, you'll always die to the same attacks because you have to learn them.
If you want to advance somewhere in UFO lunatic, you don't practice. You grab a shitload of replays and micromemorize the stages.
PCB is fun. It's dodging, it's fair, there are no tricks.
Anyone can just play it by shooting and sightreading. The gimmicks are limited to "oh that was aimed, didn't notice" and "didn't know they only shoot when you shoot them"
Everything up to IN is pretty much the same. Touhou games were slow, but casually playable.
Then ZUN decided to remove continues, and you could no longer take it easy without playing below your skill level.
I love to play BWR on Hell even though it kicks my ass. DDP loop 2 is amazing fun when you throw in 9 credits and just try to dodge. And you feel like a superplayer when you actually pull something good off. It's fun.
To play UFO, you gotta be HARDCORE. And that's no fun in a mostly casual genre.
The game simply boots you out on stage 2/3, and even if you get a .dat, you'll be stuck with your peashooter if you screw around. The game won't even let you play it.
MoF and SA were heavily bombable, but halfway in the UFO problem.
