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: Hydro Thunder
Awesome Music: A unique case regarding that unlike most racing games (and pretty much any 90s game in general) is that instead of the standard techno or metal/rock soundtrack, the game has an orchestral/rock soundtrack. It really comes to head in Venice Canals, with the intense, operatic score to go with the pace of racing at high-speeds through the old City of Canals.
The original's main theme. The Scare Chord intro combined with the quiet synth-guitar in the background crying out is just the best thing you will hear in arcades.
Funny Moments: You can race a freakin' rowboat or a model of the Titanic!
Also, smashing into various obstacles (like civilian boats, penguins, monkeys, the police chasing you, etc...) well send them flying and playing some kind of goofy sound effect.
And VENICE CANALS.
How could you forget the Tarzan scream, Yee-haws, and the "Buckle up Reggie, This one's gonna hurt!" when you fall from a really high slope, waterfall, or structure?
"If you look carefully, you will see that the graphics are made up of thousands ot little triangles." (ooohhh)
Hurricane has plenty, including the announcer using the "I Can See My House from Here" line, some random Announcer Chatter in the Area 51 level once the alien overlords have taken over, and being able to race as a rubber ducky, complete with a windup key for the boost animation.
Game Breaker: The Banshee, with it's ridiculous speed and handling as well as being the most stable in its boost. It made the rest of the boats a moot point save for the Cutthroat.
Harsher in Hindsight: The New York Disaster stage, in a game that was released two years before the 9/11 attacks.
Moment of Awesome: Lake Powell is all about this. There's a huge ramp in near the start that allows you to fly over a few rock formations, and then there's the part where you can use the back of the dam towards the end to fly over a helicopter and passing train...
P.S.: For added fun, hit the helicopter... AND the train.
You and everyone else manage to inadvertently rescue a stranded ship by leading rescuers to it.
Nightmare Fuel: Nile Adventure, about through mid-leg of the trip, has you go through a tunnel that looks like a giant snake, and then somewhat before the finish line, you encounter a weird serpent like beast that acts as an obstacle.
Polished Port: The home console versions. Not only is it easier to unlock the bonus boats, but there are extra modes depending on the console. PS1 had a career mode, Nintendo 64 had four-person multiplayer, and the Dreamcast had graphics equal to that of the arcade original.
Scrappy Level: Ship Graveyard and Venice Canals, mostly because of all the sharp turns and most boost powerups are hidden.
