* SugarWiki/AwesomeMusic: Galaga Arrangement, part of ''Namco Classics Collection Vol. 1'', has a surprisingly incredible soundtrack. Particular mention goes to [[http://www.youtube.com/watch?v=eWm1a4LzK6s Nebula Zone]] and [[http://www.youtube.com/watch?v=QkVEfvra1Vc King Galaspark]].
* ComplacentGamingSyndrome: In the original game, world-class players will start a 2-player game and play on the player 2 side. This is because player 1's score counter is only 6 digits long and will roll scores over 999,990 back to 0, but player 2 has a 7-digit score counter.
* EvenBetterSequel: To ''VideoGame/{{Galaxian}}''.
** ''Galaga '88'' to the first ''Galaga'', to those who actually played it.
** [[LoveItOrHateIt The jury is out]] on the [[NintendoHard maddeningly difficult]] ''Gaplus'', but the features it added (''your own'' TractorBeam that you can use to convert enemy fighters to your side) are pretty neat.
* FirstInstallmentWins: Good luck finding someone who's at least heard of the sequels. Subverted in that this is actually the second installment, with ''Galaxian'' being the first.
* GoodBadBugs:
** There is a very small gap in the hitbox between your Dual Ship, so there's a slim chance that you can exploit it to allow an enemy missile to slip through without losing either of your ships, but this requires very lucky timing to pull off.
** It is possible to kill two enemies in a single shot and thus have a hit ratio of over 100%, up to 200% if you only make one-bullet double hits or don't fire anymore. [[AwesomeButImpractical Not that having a >100% ratio is any useful to scoring.]]
* SugarWiki/MostWonderfulSound: The special jingle that plays if you shoot down every enemy in a Challenging Stage.
* SequelDisplacement: Far more successful and well-known than it's predecessor, ''Galaxian''.
* UrbanLegendOfZelda: The triple ship legend. However, it was finally made possible in Galaga '88.
