* CargoShip: [=McJunker=] loves mine carts a ''little'' too much.
* DamselScrappy: Rosie, to those who find her TheLoad/DamselInDistress qualities unbearable. In-universe, it's even lampshaded when she points out how many times you've had to save her bacon, and asking if you hate her.
* DuelingGames: With ''VideoGame/DinosaurKing'' and, less directly, ''VideoGame/{{Spectrobes}}''.
* EnsembleDarkhorse: Judging from the fandom alone, you would think the series is about a group of reptilian aliens and their struggles, and not dinosaur battling. It's probably fair to say some of the fans are [[JustHereForGodzilla just there for the dinaurians.]]
* EvenBetterSequel: ''Champions'', at least in terms of gameplay. The combat gains added depth due to the changes to field placement and attack ranges, and Vivosaurs can be somewhat customized in terms of color and stats thanks to Wondrous Fossils. Super Evolvers and the game's higher level cap also add more of a sense of progression, as one can't simply soar to the highest levels by cleaning every fossil you find early game.
* FandomBerserkButton: Depends on who you talk to, but one should generally be wary of calling this game a Pokémon clone.
* FirstInstallmentWins: In terms of story, the first game's is generally considered the best, both for the halfway plot twist and the depth of the second half of the game.
* FridgeLogic: After you beat the game, the game makes you shell out $20,000 for an oasis seed, because there's an area called Parchment Desert where your radar won't work because of how hot it is. How come your radar worked just fine in [[ExactlyWhatItSaysOnTheTin Mt. Lavaflow?]]
* GameBreaker:
** Compso. It can lower the opposing AZ dino's attack and defense by 90% AND it gives you a nice FP bonus thanks to FP Plus just by being in your SZ. And you can get one pretty early on.
** Raja in Champions can be found in the first area, and can evolve into Giga Raja with a Gold Fossil, which can also be uncovered early with a little dedication. By combining its new, highly-powered attacks with its ability to Charge power, Giga Raja can deal more damage than the highest possible Hit Points of any Vivosaur!
** Heracles. It has absurdly high attack, especially for a Mid-Range, and it can hurt you indirectly with its above average Support Effects and Enflame skill.
** Burst Points make cleaning fossils ''much'' easier, as they tear away huge chunks of the fossils.
** Poison in ''Frontier'' is percentage-based, so the more HP the boss has, the more damage the poison will do. This can turn even the bonus bosses into jokes.
* LesYay: With Pauleen if you play as the female character, as she does get embarrassed when she takes you by the hands.
* MemeticMutation: In addition to a guard who talks about miserable little piles of secrets, one kid gets in a "Do Not Want!" during [[spoiler: the invasion of the town.]]
* MostWonderfulSound: The little jingle that plays when you crack open an obstacle and find some money.
* ScrappyMechanic:
** Two-sided fossils. You have to clean two fossils in the same amount of time as you would for one, and Burst Points won't happen. To make matters worse, they're the ''only'' body part of that Vivosaur, meaning you have to really grind to make them viable in combat.
** Black fossil rocks can only be broken with the hammer, and if it's fragile your first swing could completely destroy the fossil inside. It's even worse if is there's a ''tiny'' bit of shell covering the edge of a fossil, as you'll have to swing and crack it even more to get rid of it.
** Giant fossil rocks are meant to be cleaned in multiplayer, so if you're in singleplayer you'll have to spend a lot of time pluses.
** ''Frontier'' gives us Paleo Pals, AI-controlled teammates who only have one Vivosaur they can use and are prone to ArtificialStupidity. They are completely mandatory for filling out your party of three Vivosaurs, as you are only allowed to control one Vivosaur in any given battle.
** Rogue Vivosaurs in ''Frontier'' spawn randomly at any time and they can interrupt your fossil cleanings, sometimes as soon as one starts.
* SidetrackedByTheGoldSaucer: Fossil cleaning is ''addicting''. It's possible to be on chapter 2 and have a bunch of upgrades and powerful Viviosaurs. The upgrades that let you find new fossil rocks make it even ''more'' addictive.
* TaintedByThePreview: Some review outlets accused the game of being Nintendo ripping off itself based on concept alone, despite the fact that it doesn't actually play all that much like Pokemon.
* ThatOneBoss:
** Saurhead. The issue is not that he's exceedingly strong, it's that you have to play ''extremely'' defensive, because [[WeCannotGoOnWithoutYou losing even one vivosaur makes you lose.]]
** Zongazonga in ''Champions'', primarily because his defeated Vivosaurs resurrect every other turn, hit every member of your team for good damage, and can greatly cripple their stats.
* ThatOneSidequest: Champions' Hare Club quest requires you to clean 100 fossil rocks to 80 points or better, many of which are extremely difficult, while wearing a tacky rabbit mask.
* TheyChangedItNowItSucks: ''Frontier'' gets quite a bit of this from fans of the first two games, for reasons ranging from having a smaller roster of Vivosaurs to the complete overhaul of combat, especially after the improvements made to it in ''Champions'', and only having direct control of one Vivosaur in your party. The RealIsBrown cleaning system is also a point of contention.
* ToyShip: The main character and Rosie; her crush on him is particularly painfully obvious. [[spoiler: But near the very end of the game, you can choose to have him end up with Duna instead.]]
* TheWoobie: Rosie realizes she's TheLoad, and is genuinely sorry when you have to help. She even asks if you hate her at one point, and you ''can'' say yes.
