History YMMV / RaySeries

** ''Ray'z Arcade Chronology'' for UsefulNotes/NintendoSwitch, UsefulNotes/PlayStation4, and PC once again has Creator/{{M2}} hitting it out of the park with their masterful ports. The arcade versions of all three games are included in the package, with ''[=RayStorm=]'' in particular getting a new HD version with the correct aspect-ratio and all the features of the arcade original (such as adjustable per-stage difficulty, but without the infamous "Training Mode" mechanic from the Creator/WorkingDesigns version) and ''[=RayCrisis=]'' finally seeing an ArcadePerfectPort for the first time.[[note]]The [=PS1=] and Windows versions allow the player to freely choose their three middle levels, has some changes in the way Encroachment works, and loosens the requirements for [[TrueFinalBoss Infinity]]. The mobile versions use alternate control schemes if only playing using the touchscreen, and even if one uses a compatible wireless controller, the requirement for Infinity is loosened from 20% to 25%, so that's not accurate to the arcade version either.[[/note]] All three games have optional gadgets that show real-time gameplay data, multiple rapid-fire options, manual and {{auto|save}}matic save states, and the two 3D games [[SalvagedGameplayMechanic having an option to disable firing a Special Attack with simultaneous press of the shot and laser buttons]] to instead use a separate button for that purpose. It also features the ability to play these games with the original arcade soundtrack or the arranged soundtracks from their home ports as well, allowing players to enjoy these games with their favorite soundtrack. The collection also features online leaderboards for all three games with shareable replays similarly to ''[=RayStorm=] HD''.

** Conversely, the requirements to face the TrueFinalBoss, Infinity, in ''[=RayCrisis=]'' are a little ''too'' lenient. In the arcade version, once you have cleared five different maps on the same account, from then on reaching [[FinalBoss Dis-Human with less than 25% Encroachment]] forces the player to fight Infinity after Dis-Human. A decent player can meet that requirement even without trying too hard, since if they are between 25-45% Encroachment going into the last boss before Dis-Human, they can potentially kill the boss fast enough to reduce the Encroachment below 25%. And if Infinity is encountered, but the player does not actually finish the fight (likely due to running out of coins, or just getting fed up with the fight), the map isn't considered completed, while defeating Dis-Human without triggering Infinity ''does''. This means if the player is trying to complete maps to unlock the stage select feature, they're forced either to fight a new final boss that is quite likely out of their league and will have them feeding lots of extra money just to mark the map done, or to DoWellButNotPerfect and intentionally let enemies live and prolong boss fights to keep Encroachment relatively high to avoid fighting that damned BulletHell egg.

** The [=PS1=] port of ''[=RayCrisis=]'' loosens the requirement for the TrueFinalBoss from "clear at least five different maps on your account, then defeat [[FinalBoss Dis-Human]] with less than 20% Encroachment" to "just clear any three maps of your choice, then reach and defeat Dis-Human with less than 5 continues". On one hand, this makes it easier to get the true ending. On the other hand, it forces 1-credit clear attempts to include said true final boss; there's no toggle to force the "normal" ending after Dis-Human.
