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: Dragon Ball Z Budokai
Character Tiers: Not as bad as some other fighters but they're definitely present. Omega Shenron is top tier due to powerful combos and by default having 7 base ki bars, meaning he fills up to max ki without having to charge, and Piccolo, Cell, and Dabura are up there with him because of their fast ranged physical combos. Bottom tier is Saibaman and Mr. Satan.
Contested Sequel: Infinite World is this to Budokai 3. Reasons for this include it actually removing characters and features and not adding any new stages, which makes it feel more like an expansion pack than an actual sequel.
Omega Shenron: (Folding arms, not amused.) I don't grant wishes for candy!
In one bonus storyline in Dragon Universe, Vegeta goes behind a bush so he can do a Fusion Dance with Goku without being seen "dancing around like a fool." Goku mistakes him for... taking care of business.
Goku: Well, when you've got to go, you've got to go.
Saiyaman...justSaiyaman. His ultimate is merely him introducing himself and pulling off a pose! Do it right and he gets an attack boost. Screw it up and he looks ever so stupid.
The What If? in the first game where Cell accidentally absorbs Krillin. Made even funnier by the fact his the onlyWhat If? where the villain loses. And then it turns out it was just a nightmare Perfect Cell was having during the 10 day Cell Game waiting period.
Yamcha goes up against Cell after he's been weakened by absorbing Krillin... and stillloses.
One small one in Frieza's What If? after killing Goku. He's standing there panting...and then merely grins and "Hmph!"'s...and then you notice he had a tooth knocked out.
Goten's winpose after beating Videl. He looks so adorably concerned that Gohan'll be angry at him.
The way some pre-fight dialogue can match up even if the characters don't have special intros. case in point...
Majin Buu: Do you like chocolate? or Yamcha: Think you can handle this?
Crowning Music of Awesome: The game's soundtrack is commonly considered to be very well done, especially the opening themes from 2 onward.
Fridge Brilliance: Notice how in Infinite World, GT Goku's Super Kamehameha is the same one he blew Commander Black to bits with in the movie The Path to Power., which is based on the original Dragon Ball. Why's this? Because technically the Goku in that movie was GT Goku thanks to using the same colour scheme as GT's depiction and his art style (facial structure and such) more resembling GT than the original Dragon Ball!
Game Breaker: Piccolo's Light Grenade in Budokai 2 & 3. It only costs half a ki bar AND does some pretty heavy damage. In the first Budokai the damage it does isn't as much though, and you can't spam it like you can in 2 & 3.
Narm: The PAL version of the first game uses the Japanese voices whilst having an alternate translation for Story Mode...which features weirdness like Vegeta calling people "Aunt Sallies" and Bulma expressing sadness at how Goku "was able to escape from Namek" (seriously) while the cutscene showed him...kinda failing, (He escaped but besides that...) and at one point translates Cell's angry growl of "Shikusho!!" ("DAMMIT!") as "Shucks!!" On the other hand it does subtitle one of Android 18's lines as "Oh Crap..." and has a few instances of "Damn" here and there.
Scrappy Mechanic: The Luck-Based Mission, in which you have to press a button and hope that your opponent also presses the same button. You've got a very slim chance that you'll press the same button as they do every single time. For weaker opponents, this isn't so bad, but it could easily cause you to lose the fight against stronger opponents like Cell and Kid Buu.
To clarify, it added in beam struggles, the ability to fly up or down while dashing, teleport and dodge counters, more individualized physical combos for every character, greater variety in the special moves (most characters have a beam special and a physical combo special with varying properties), as well as the Dragon Rush mechanic and a new quick time event for Ultimate moves.
Suspiciously Similar Song: Many of Kenji Yamamoto's works sound eerily similar to songs by Finnish power metal band Stratovarius. The most obvious is Budokai's "Warrior from an Unknown Land" compared to Stratovarius's "Infinity". note Doesn't make Budokai's soundtrack any less awesome, though. In fact, years after the Budokai games were released, Yamamoto was fired because Toei found out about his plagiarism. The HD collection of the Budokai games uses a completely different soundtrack.
Visual Effects of Awesome: Most of the ultimates look fairly impressive in the first game, and then its cranked up big time from 2 onward, especially when you use certain world-destroying ultimates that change the arena into one of the two "ruined" stages. Using a sphere-shaped or explosion-based super move gets one of two scenes of the ball exploding on the planet's surface giving the player an epic view from the planet's orbit. Using a beam type ultimate, you see the beam shooting outward from the planet, also viewed from orbit. And the beam is gigantic if said successful ultimate was Super Saiyan 4 Gogeta's 100x Big Bang Kamehameha.
What Could Have Been: The unlockable "Memories of" voice files in 3's Dragon Universe mode hint at stories that never made it in, including a possible alternate outcome to the final fight with Kid Buu having Vegeta wish for Goku's tail to grow back and Goku reaching Super Saiyan 4 as a result, as well as a story for Kid Goku involving him travelling through time or being wished back into a kid (ala GT though the Kid Goku here is Dragon Ball-era Kid Goku.)
What The Hell Casting Agency: In Budokai 1, its easy to wonder why Great Saiyaman, a Buu Saga character mind you, made it into a game that only went up to the Cell Saga.
