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. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: TIE Fighter
Even Better Sequel: A tough contest, as X-Wing gets a lot of deserved love from the fans, still Tie Fighter includes a new and unique perspective, lot of improvements and new features. It also got better reviews and universal acclaim.
Game Breaker: Manages to have two, and one (the Missile Boat, King Hell God Emperor Starfighter of Death no less) was developed to counter the other (the TIE Defender). The Tie Defender was this because it essentially was better than everything else at everything, it was the faster craft, it had the best shields, by far (it's hull wasn't anything to brag about but it shields meant that was moot), and the best armed. The Missile Boat, at its named implied, was loaded with missiles that could allow it deal with anything, and it boost that drew power away from its laser cannons and shields allowed to double its speed, the thing already being pretty fast, allow it move faster than the Tie Defender. Because they were too powerful, production of these special craft was ceased in case a future traitor would get their hands on them. (Both would be removed from the multiplayer sequel, whose craft library had entries that explicitly stated that it was due to their brokenness. The last game, X-Wing: Alliance, would end up using slightly toned down versions, although not enough so to avert the trope.)
The previous game allows you to use the Y-Wing to take out the shield generators on a Star Destroyer, then use a few ion cannons to disable the vessel. In this version, you could blast the generators with an Imperial Gunboat or TIE Defender, but improvements to the shield system no longer cause shields to instantly drop (and instead, you need to rely on rockets or space bombs). However, a capital ship without shields is paralyzed instantly.
God-Mode Sue: A vehicle example in the form of (what else?) the Missile Boat and to a lesser degree the TIE Defender.
