For the first game's YMMV tropes, see here.
- Complete Monster:
- Third game: Nobuteru Morita is the greedy CEO of the Morita Group. Approached by Daigo Hazuki to help fund the development of Central Island in order to avoid bankruptcy, Morita gave him everything he needed in return for Hazuki's wife, whom Morita forced to birth him a child of his own. Knowing that Central Island was built over a gas field that could cause potential natural disasters, Morita refuses to do anything about it, hoping to make more money by establishing control over the energy resource. Morita and Hazuki fire their expert geologist Ishizawa and have his daughter Keiko killed in order to prevent word of the gas field from leaking, and when natural disasters eventually strike the island, Morita attempts to abandon everybody and save himself.
- Summer Memories:
- Kiyoko Maeda, a supposedly kind old lady, is revealed to be the head of Snake Snake, a criminal organization that specializes in human trafficking. Using the disaster as a way to lure in survivors to be sold as slaves, Maeda uses her partner Keith to manipulate people into helping them out, only to betray them afterwards. Having been in the crime game for quite some time, once the survivors escape her ship, Maeda tries to have them all killed by Keith.
- Notuboi and Kanadakai are two thugs wandering in the city during the disaster, rumored by many townsfolk to have assaulted many women. When they first meet the protagonist accompanied by Kanae, they tie both of them up and plan to rape Kanae later, only failing due to the latter having escaped with the protagonist. Upon finding Yayoi, they rape her before fleeing, leaving her traumatized. Months after the disaster, they are still around, continuing their wrongdoing, eventually finding Hiroko and trying to rape her.
- Contested Sequel: The third game is considered by many fans to be the weakest in the series, due in part to being held back by the technical limitations of the Playstation Portable. Compared to Raw Danger having six playable characters, the third game only has the male and female protagonists, both of which follow the exact same story, the Stress Meter is unwieldy compared to the first game's thirst bar and the second game's BT bar, and it also lacks any vehicles for the player to pilot.
- Even Better Sequel: While the first game is respected enough for its innovative setting of a (seemingly) natural disaster, its sequel, Raw Danger, managed to iron out most of its predecessor's kinks by having more interesting levels to explore along with a more ambitious story revolving around multiple playable characters, each one having several different endings to unlock.
- Jerks Are Worse Than Villains: The villains of Summer Memories include a pair of rapist and slave trafficking organization but they either didn't have much screentime or provide the story some twist. Then there is Kumazawa, a sleazy shopkeeper that the protagonist encounter throughout the game who uses the disaster as an opportunity to earn a quick buck. Regularly seen behind the counter of a convenience store, that he isn't even an employer, he charges customers in need of supplies at exceptionally high price (a bottle of mineral water can be as high as 50,000 yen) and even increase the price within seconds. Not even a mother with her infant child are spared from his greed. On other occasions, he can be seen looting from destroyed houses for valuables.
- Magnificent Bastard:
- Raw Danger: Mayor Goldstein, real name Apolon, is a well-respected politician who masterminded the degradation of Geo City. Having originally been a citizen of Cascade Village, after witnessing the government solve a virus epidemic within his village by burning it all down and building Del Ray over the ashes, Goldstein sought payback. Becoming the mayor of Del Ray, Goldstein used his connections to secretly create the deadly Echidna virus, which he'll unleash on the people of Geo City during its grand opening, even having the city flooded as a distraction. Having anyone who tries to reveal the truth killed, while able to recruit traitorous comrades to his side and potentially get away scot-free, Goldstein will even resort to cold-blooded murder to ensure his plan succeeds.
- Kowareyuku Machi to Kanojo no Uta: Ayami Hazuki and her older brother Keisuke Hikawa desire revenge on behalf of their mother. After finding out her mother died from shock via circulating rumors, Ayami launches a plan to kill those behind her dark past, with Keisuke teaming up with her to help ease her pain. Planning to have geologist Ishizawa kill Daigo Hazuki and Nobuteru Morita, when Hazuki and Morita tasked Keisuke to murder Ishizawa's daughter Keiko, Keisuke dated her until the two became engaged, whereupon he killed her and covered up her death as a suicide. When a series of disasters strike Central Island, Ayami poses as a hapless teenager to get survivors to assist her in killing Hazuki and Ishizawa, while Keisuke poses as a detective who tracks down and kills Morita in his own building. Able to overturn Ishizawa's attempts at killing her, Ayami saves Ishizawa from falling to his death after she regrets her actions, and is able to file a testimony against Hazuki, completing her and Keisuke's plan.
- Narm: The first two games' English dubs aren't remembered fondly at all, with the stiff at best and robotic at worst voice acting clashing horribly with the emotional moments they throw at the player.
