These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way.

YMMV: Ace Combat 5: The Unsung War
Crowning Music of Awesome: Favors a more Western-inspired orchestral score over the Rock/Electronic tracks in the previous games, all of which is composed by many signature composers of the Namco Sound Team, including Tetsukazu Nakanishi, Keiki Kobayashi and Hiroshi Okubo, while also introducing new assets, such as Junichi Nakatsuru, Katsuro Tajima and the ACE COMBAT5 Chorus Team, all of which performed by the Warsaw Philharmonic Orchestra. Throw in a few of the classic synth/guitar segments from the previous games, some Ominous Latin Chanting, and an Oscar Bait theme song performed by Mary Elizabeth McGlynn to boot, and you get pure distilled awesome. Some highlights:
Game Breaker: The Raptor or any fighter with XMAAs or XLAAs in the final mission becomes a literal example where the first fight can be finished in about ten seconds. It's supposed to last much longer, but get it right and the in game speech cannot keep up with you winning so easily.
Even better if you take the FALKEN and its TLS to the final mission - one sweep of it through the enemy aces, a few minutes of uninterrupted monologue, and then cutting the goddamned SOLG in half with another sweep.
Oddly enough the UGB, and only for the last mission on the assault on SOLG specifically. A single direct hit on SOLG can take out half or more of the designated targets and makes what should be a challenging mission a breeze. The developers of the game likely didn't anticipate this because the UGB is an air-to-ground weapon only and the SOLG can only be locked on with air-to-air weapons (though being an unguided weapon, that doesn't exactly stop the UGB from being able to hit it).
Large Ham: Allen Hamilton, Ashley Bernitz, and Michael Heimeroth in the last missions.
Surprisingly Improved Sequel: To 04, being about twice as long as any other game thus far, and also adding the new squadron control mechanics and a more character-driven narrative, this game often ends up as many fans' favorite. On the flip side, the same two attributes mentioned above are why some other fans dislike it.
