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: Tony Hawk's Underground
Crazy Awesome: A lot. Notably, doing a McTwist over a fucking police helicopter.
You can play as Bigfoot riding a chainsaw in THUG2.
Cowboy Bebop at His Computer: When Underground 2 is installed on a Windows Vista or 7 computer, the games browser identifies it as Tony Hawk's Pro Skater 2.
Good Bad Bugs: THUG2 has a brilliant one in the Los Angeles level in Classic Mode. The level was a remake of the one from Tony Hawk's Pro Skater 3 and is built around the same code, being virtually identical. Because of the additions since its original release - getting off your board and skitching) it is possible to jump onto an area of highway you were originally not supposed to go to. There, you can skitch on one of the cars and this will enable you to enter the background, underneath the level. The ground around is solid and you can walk around for quite a while.
Money, Dear Boy: Played with. The losing team of the World Destruction Tour has to foot the bill for all damages caused by both teams during the contest; and Nigel Beaverhausen (Writer-Producer-Director) tries to persuade them to let him film and release the footage of the tour, before resorting to doing it without their permission. Both Tony and Bam agree to let Beaverhausen release the footage after he offers to foot the bill, once they find out the bill is $21,000,000 so far (they are in New Orleans when they make this agreement, with still one leg of the tour to go).
Sequelitis: The second game to those who weren't overly thrilled to see THUG's surprisingly good story followed up with "Jackass: The Game".
Take That, Scrappy!: After inducing much rage in the audience of the first game, Eric Sparrow spends THUG2 screaming like a little bitch and pissing (and shitting) himself. By the time he's eliminated from the tour, even Bam's actively trying to get rid of him and he's on Bam's team.
The Other Darrin: Possible - The first game forced all created skaters to use the same voice (Although it changed depending on the gender) in the story mode; whilst the second game (Despite it being the same character) allowed the player to choose from a number of voices, including the voice from the previous game.
