Crash Bash/YMMV

Awesome Music: "Desert Fox" and "Metal Fox", two military march pieces very reminiscent of the theme to The Great Escape.
- The medieval themed "Dragon Drop" and "Mallet Mash".
- "Pogo Padlock", a funky tune which has a big city feel.
- "Pogo Painter", a funky remix of the Crash 3 theme.
- "Sky Balls", a goofy military-flavored piece.
- The banjo piece for "Swamp Fox", which will get stuck in your head, especially since the level in story mode is really difficult.
Game-Breaker: A lightning bolt power up on Tilt Panic is pretty much an instant win. Because of the tilting gimmick, more often than not all the characters will just slide right off the stage without you having to touch anything. Compare it to the other levels where if they get struck by lightning you still have to take care of pushing them off, and it's pretty silly how much it trivializes this particular arena. In fact, your best bet with the gem and crystal challenges is to just keep going until you get a lightning bolt.
Rooting for the Empire: This game is made as pure catharsis for fans of the Crash villains. Not only can you play as most of the key bad guys here, you can get a "bad ending" where you help Uka Uka outright take over the world! And if you have a second player handy, you can have them play as a good guy so you fight them directly to win the game. You can have Cortex beat the living tar out of Crash!
The Scrappy: Rilla Roo, who is a Flat Character (his personality is literally "monkey") that never showed up in any of the Naughty Dog games and also copies Dingodile's gimmick of being a Mix and Match Critter (plus being part Kangaroo, an animal already represented in the series in the form of Ripper Roo). He might have a few fans here and there, but otherwise most people either dislike him, don't care for him or simply forgot he existed.
Scrappy Mechanic: While many of the mini games are fun, the rule of winning them three times over can get tedious, leading to up to a maximum of nine rounds per mini game. Even in standard Battle Mode, you can only decrease it to a two round victory (making a five round game at max). Mercifully the gem and crystal challenges require only one victory, however, the relic challenges require you beat them two or three times in a row.
Surprise Difficulty: Adventure Mode looks like reliable and fun Crash fare, but anyone who has played the last four Crash games will notice how rotten this one can get. Might also count as a Sequel Difficulty Spike in relation to the Crash series as a whole. The cooperative mode, while no pushover, is easier since it evens the odds with 2-on-2 games.
That One Boss: Like Crash Team Racing, the bosses are a LOT tougher in this game. Even Papu Papu puts up a fight, like in Crash Team Racing.
Tough Act to Follow: To Crash Team Racing. That game was a Follow the Leader to Mario Kart, but was just as good, and some would argue even better. Crash Bash, however, was not nearly as successful in its imitation of Mario Party, for a number of reasons (less variety in the mini-games, cheap A.I., a boring hub that pales in comparison to the Mario Party game boards, and Nintendo Hard difficulty).
