YMMV: RAY Series
- Awesome Music: Yes, indeed!
- Genius Bonus: If you're good at history of the Roman Empire, you'll understand a lot more about RayStorm, including the bosses and the storyline.
- Most Annoying Sound: If you're not very good at RayCrisis's Special Mode, the Encroachment Meter will often spike above 90%, resulting in repeated alerts of "Encroachment over 90%!".
- Narm: The Japanese version of RayCrisis has one of the bosses named "Sem-Slut," renamed to "Sem-Strut" in the English localization. This wasn't the case with the European PC port.
- Porting Disaster: RayForce's (Layer Section) PC port is servicable, but it comes with some glaring problems that has gotten worse over time. One of them being the game screen itself, which has been reduced to a square to fit in a 4:3 aspect ratio that was never intended for the game. Unlike the PC ports of its sequels, the fullscreen scaling does not work properly on newer 16:9 monitors and often results a smaller screen size with occasional color distortion despite being running in 640×480. Another, much more game-breaking issue is the game's speed, where it plays ridiculously fast on faster computers to the point of it being unplayable. While the latter can be addressed with a simple .dll fix (if you have the game disc), but fullscreen issue can only fixed by a third-party program such as D3DWindower to play the game in an appropiately sized window. Other problems includes missing effects and backgrounds, some of the music tracks don't play properly (such as the Game Over music), and you don't have the disc, then enjoy playing the game with no music at all.
- The Sega Saturn port of RayStorm (Layer Section II) introduces some novelties it has over the PlayStation version, such as new CGI cinematics in between stages and a playable R-GRAY 0 outside of 13-Plane Mode, but due to the Saturn's notorious 3D handicap, the graphics were understandably downgraded but its biggest problem was its frame-rate, which bogs down substantially when the action intensifies and can cause input lag.
- Polished Port: The PC port of RayStorm and RayCrisis has higher resolution than their arcade counterparts (at 640×480), and better sound effect quality than the PlayStation version (you can hear the sound of R-GRAY 2's laser beams and the ambient machine noise of Yggdrasil). Despite being released for Windows 95/98, both games runs quite well on modern systems and those with higher-end machines can enjoy the almost non-existent loading times. The only downside of the PC version of RayStorm that it lacks the optional TANZ soundtrack of the Extra Mode the console versions have and requires the disc to run the game, and RayCrisis' port is based on the PlayStation version which lacked co-op multiplayer.
- The HD version of RayStorm may not have the PC version's superior sound quality, but the visuals has been nicely upgraded for HD and you have an unlockable R-GRAY 0 that plays like the RVA-818-X-LAY fighter from RayForce instead of an inferior R-GRAY 1 and the Difficult but Awesome R-GEAR to play around with, along with leaderboads and sharable replays.
- Scrappy Mechanic:
- Only one word for RayCrisis — "Encroachment".
- Working Designs did a bit of Easy-Mode Mockery for RayStorm; specifically, if you set any stage's difficulty below 4, the game puts you in "Training Mode", which ends the game after Stage 4. The game lets you set Stages 5-8 to below level 4 difficulty, but in a display of oversight on Working Design's part, you will still be denied entry to those stages.
- Tear Jerker: The ending of RayForce. Our un-named heroine dies when the resulting explosion hit her RVA-818-X-LAY fighter, destroying it along with Earth. The final seconds of the credits pans to what remains of the wrecked fighter, and then we see the dashboard displaying Mission Complete just before the ship's power finally dies.
- Also, the true ending of RayCrisis due to being Doomed by Canon.
- RayStorm as well. Consider that you just committed genocide of an entire planet in order to stop a rebellion. The 13-ship mode makes it even sadder, as Earth itself got destroyed as well, and the player's ship was left to drift in space, never to be found again.
- That One Attack: The tricky-to-dodge "Taito Homing Lasers", which have also appeared in the Darius series.
*BOOM* RAY 3 to continue present tactics.
