* SugarWiki/AwesomeMusic - All of the battle themes count, especially for the [[https://www.youtube.com/watch?v=jflkqzDMxBU Fire]], [[https://www.youtube.com/watch?v=t6WbnLcPOfg Ice]], and [[https://www.youtube.com/watch?v=dRceZrqkBBQ Forgotten]] planets.
* SugarWiki/FunnyMoments: Halfway through the game, Psyme falls victim to an apparent illness after Ian Recker gave her a kiss. [[BizarreAlienBiology Knowing nothing about Krill physiology]], Recker assumes that [[MistakenForPregnant he impregnated her]]...[[MissConception somehow]]. (Two Krillian healers tell him that "[[LeaveTheTwoLovebirdsAlone this is a special moment between you two]]", not helping his case any.) He then takes her back to the Forest Planet to dip her in a pool to allow her to "recover", and the expecting dad is instead greeted by a perfectly healthy Psyme, now sporting a new set of [[PowerGivesYouWings fairy-like wings]]. After chastising him for [[ArtisticLicenseBiology failing Krill physiology 101]], she gives the wings to him for use by his parasite, admitting that they only grow on Krill females whenever they feel...[[ThePowerOfLove close to a person]]. The game then congratulates the player for acquiring Psyme's gift by taking a jab at Recker's, erm..."manliness":
-->"You got the Girl Wings! Wings like a '''GIRL!'''"
* GameBreaker - Some gun data combinations are criminally effective, particularly any combo that renders the user completely impervious to damage.
* NightmareFuel - The Forgotten Planet. It's a dark and empty planet, with ghosts and skeletons littered throughout. The boss of the planet, The Ghost of Iot, is also very creepy, especially after the fight when it creates a heavy fog of spirits that leads to a tense escape sequence. [[ParanoiaFuel The difficult random encounters, escape sequence, and Game-Breaking Bugs only add to the tensions.]]
* SidetrackedByTheGoldSaucer - The game's final [[VideoGameTools Video Game Tool]] is given to you directly before the events which set the game's climax into sequence. If you want HundredPercentCompletion, the fate of the world will have to wait while you backtrack through nearly every stage up until that point.
* ThatOneBoss - The Ghost of Iot is known for giving many players fits, largely due to a somewhat random attack pattern combined with lots and lots of health.
** Not to mention the GameBreakingBug.
* ThatOneLevel -
** [[EarlyGameHell The first visit to the Fire Planet]], which involves a long and tedious quest to find three fissures scattered around the planet. The random encounters are [[DifficultySpike much more frequent and difficult]] compared to the Forest Planet, with many enemies with high defense and offense. Even worse, you have to travel across a very wide map with [[CheckPointStarvation very few save points]] to find all three fissures, so you may lose a lot of progress if you're unlucky. Thankfully, you can get much better Gun Data there, and the game becomes more fair and enjoyable afterwards.
** The Sand Planet, where one quest requires you to slowly sweep every square inch of sand in one area with your scanner to find fossils. Because of all this walking around (and having the Scanner out stops you from using the Boots to speed it up), there will be lots of RandomEncounters. And one random encounter in this zone requires you to shoot down ''99'' enemies, 3 to 4 times what any other encounter requires. The repetition becomes ridiculous if you can't find that one last fossil.
** The Forgotten Planet as well. A large, sudden DifficultySpike notwithstanding, the aforementioned {{Game Breaking Bug}}s can make playing through this stage a much bigger pain than the Sand Planet ever was. In fact, the Website/GameFAQs board for this game is largely full of threads made by people who wonder if the Forgotten Planet was even playtested.
