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: Jak II: Renegade
Complete Monster: Baron Praxis betrayed the real ruler of Haven City, booted him out into the Wasteland and transformed Haven into a totalitarian empire, loaded with ridiculously cruel laws, a corrupt police force and indifference to suffering and poverty in general. On top of that, he has no qualms using human lives in his Dark Eco experiments. While he does go out of his way to give the REAL Big Bad of the game loads of Eco just to keep him and his creatures out of the city, it's obviously just to keep control of his empire and not because he cares about the people in it. His moment of sacrifice makes up for very little of what he's done.
Even Better Sequel: A notable example, where not only the whole game experience is completely revamped for the better, but just about everything else, be it technical, gameplay or story wise, was as well.
Fridge Brilliance: In the part of the game where you storm the palace, and when you leave the small conference room near the baron's throne room, ever wonder why you're greeted with a turret stationed outside? Simple: the Baron uses that to assassinate his rival diplomats when they leave!
Goddamned Bats: The Krimzon Guard. You do NOT want to hit one or otherwise give them cause to chase you during a mission, because they WILL fuck up your attempt. And then there are the missions where they automatically chase you...
Good Bad Bugs: A well known bug which allows the player to access and explore Sandover Village as it appears in the game's opening. This is achieved by opening the disc tray during the opening cutscene, pressing triangle, and reinserting the disc. The game will drop Jak outside Samos's Hut, complete with Metal Heads flying out of the opened rift gate. At this point Jak will be unable to move; this is easily fixed by choosing 'restart mission' from the start menu. The area fully accessible, though it's surroundings only lead to bottomless voids. There has been some debate regarding the presence of Krimzon Guard crates in the village houses - some people claim that this proves the glitch was intentional, while others attribute it to the area simply being copied and pasted from the first game, with the Krimzon Guard crates automatically replacing Scout Fly Crates because of how it was coded.
Nightmare Fuel: The boulder/giant spider chase sequence in Mar's tomb.
The Tombstone puzzle in Mar's Tomb is abundantly creepy. By extension, the atmosphere in the tomb is generally pretty unnerving for some players.
That One Sidequest: If you're going for all 286 Precursor Orbs, be prepared to swear up a storm at the coliseum races. Finishing the races is difficult. Winning them takes immense patience. But to get all the orbs, you have to beat a certain time on each race, and that time is much lower than what is required for 1st place.
