If you liked the Cage of Eden manga, the Anime-Planet community thinks you'd like:
Natsu, Arashi and a few dozen others had gone to bed like any other night when they woke up... somewhere else. In this new post-apocalyptic future, mutated plants and animals lie in every direction and mankind is long extinct. Scientists of the past predicted that a meteorite would strike Earth and render the planet uninhabitable, so they devised a plan: they would cryogenically freeze five teams of young adults and have them revived by a computer when life is again sustainable. Seven people formed each team along with a guide specially trained to survive in the wild, and seven caches of supplies were left to be found. Together, the teams must try to survive in a new and hostile world, inadvertently finding the other survivors and clues to their circumstances along the way.
I personally think both of these manga are very good reads. Although the ending in Cage of Eden was somewhat rushed. The two manga are similar because they both deal with teenagers trying to survive in an unknown place with lots of strange creatures. The main differences are that there are not nearly as many deaths in 7 Seeds as there is in Cage of Eden and there is also less ecchi. I thoughly enjoyed both manga and I suggest that if you've tried one you should try the other.
Reality TV has hit a new and disturbingly graphic low with ‘The Program,' a television series in which a purposely chosen ninth-grade class is forced to fight to the death on a remote island. With only minimal survival gear and a random weapon, each student must survive and kill their friends until only one winner remains; if the group refuses to play, all of its members are killed by the electronic collars around their necks. Girlfriends and boyfriends betray each other, friends are brutally slain by their closest companions and alliances are made and broken. On screen for the world to see, only the strongest will survive this horrific, sadistic game...
Both sexed-up tales of survival take place on an island. A group of students have to fight to survive, all while providing the reader with plenty of ecchi elements. "Cage of Eden" certainly has more ecchi, but "Battle Royale" is much more explicit.

Medusa is a mysterious illness which causes the body to petrify shortly after infection, found throughout the world and steadily increasing the death toll. After losing his son to the disease, a wealthy gentleman used a large portion of his fortune to turn his medieval castle into a state of the art cryogenic facility. 160 lottery winners were chosen to be frozen until a cure could be found, one of whom is Kasumi - a twin whose sibling was not one of the chosen. Along with a group of others Kasumi awakens from her cryogenic chamber, but not to the same world she left it: prehistoric monsters roam the now-abandoned castle and eat the survivors, while endless giant thorns rise all around them. Against all odds, Kasumi and the others must now try to survive the horror of their situation and discover the truth behind what's happening, all the while waiting for the Medusa to finally claim their lives...
A group of people find themselves in a mysterious and sometimes dangerous place, with abandoned structures filled with further mysteries. Both Cage of Eden and King of Thorn belong to the same school of storytelling as the popular US TV series Lost, although it must be said that they do a better job of keeping the audience engaged with the storyline.
