I could swear this was intentional. 
I'm keepin' it, anyway!
Blimey, it even preserves your custom playlist in Attract mode.

Badass.
Nothing says what time it is quite like a Gradius III reference.

Haha, I'd totally forgotten about the PS2+PC's interlacing issues... I thought this was looking rather nicer than I recalled!
I'm surprised at how tolerable I've found III's ship speed, this time around. Really disliked it BITD. Going between it and I+IV, whose default speeds never bothered me at all, I think III's total lack of horizontal pan (IV's is variable, I is always-on) creates an illusion of the ship moving slower than it really is, relative to the others.
Gentlemen, Start Your Raidens 

Slowest of the lot is Raiden IV's mkII, a tradeoff for its br00tal DPS. IV's Fighting Thunder is the inverse. III is in the middle, and feels uncannily close to I; like Moss were really striving for a 1:1 transfer to locked pan + polys. Note how Raiden I's ship reaches the endpoint of its GIF's first frame, marked by the shadow's lower-left edge, at the same time III hits the edge of its playfield before doubling back.
It helps that locked pan is an approach I decidedly prefer nowadays, especially in Toaplanesques and other snipier games. III's relatively tiny hitbox helps a lot, too, compared to other snipefests like Trigon and HachaMecha Fighter, where you can see a bullet coming, start to move aside, and get killed by a graze, making pre-emptive movement vital to avoid being caught flat-footed. And like every other Raiden, III's not a twitchfest; far more about well-routed microtaps and cutbacks, with improv typically reserved for error correction, often accompanied by a judicious BOMBA.
Old buddy's got it where it counts 
...all that ACA Gun Frontier I've been playing lately probably helped, too.
I just wish III+IV Maniax had a 1P/2P side switch, ala ACA Raiden; can't seem to figure out a way to play as Blue Ship (only got one controller). Is there any way to do this on PS4?
