Here. A memory-loss game, where characters are reborn into the world of "Edensphere", which just happens to be a giant tree, with no memories and no clue of who they are save what was in their birth dream.It ran from 2008 to 2011. The setting was kept open as a sandbox afterwards, although activity there has largely petered out. Although the game ended before the mass-migration to Dreamwidth, the players decided to archive the game there anyway just in case. (Individual character journals vary wildly on whether or not they were ported.)
All Just a Dream: The entire game was a hallucination in the 23 seconds between the time Remmy stabbed Renée and her death.
Amnesiac Dissonance: Fairly common. Characters show up wiped of their histories, with only whatever happened in the birth dream and any inherent personality traits and Character Tics.
Ax-Crazy: There have been several of these, unfortunately. A disproportionate number of them seem to find work at the butcher's shop, to the point where the shop now offers a substantial monthly bonus for not killing anyone in hopes of attracting some employees who aren't dangerously insane.
Butt Monkey: Any of the characters can have a nasty streak of misfortune when their mundane decides to take advantage of various "events", the state of the Wilderness, and player plots. Cloud's mundane admits to liking how he reacts to pain and adversity.
Cast Herd: There are several "families" or "harems". And the butcher's.
The Chains of Commanding: Bastet (Yoruichi Shihohen) eventually one of the Sphere's de facto leaders through her natural assertiveness and just being around a long time. She only let her guard down around a very few people.
Character Development: Loads. Several players took the opportunity explicitly to develop their characters down paths left open but unexplored by canon, or to figure out how a loss of memory and driving purpose would alter that character's trajectory.
Curiosity Killed the Cast: There's a metaplot. Learning too much about it tends to result in the curious character dying, either because of the tree itself or an attack of the giant wildlife.
Death Is Cheap: In most cases - the exceptions are when players drop a character and have them die rather than vanish - after at least three days the character is reborn with a new birth dream, possibly losing some prior memories as well.
Subverted these days. A loss of some kind is required after most player-initiated deaths, be it memories or a body part.
Dysfunction Junction: Most events in Edensphere are opt-in and can largely be ignored if a player so chooses. Ironically, a few opt-in events have caused far more drama/trauma game-wide (through multiple player-driven plots) than the single biggest event in the game that could not go unnoticed (The Great Sphereferno, see Moment of Awesome).
These events are: Evil Twins (original flavor or redux), Revolving Reveries (Sir No Longer Appearing In This Game), and Radio Memories (January 2011).
While There Are No Therapists, the reason these clustered player-run plots usually affect the whole game is that if you aren't in direct line of the drama/trauma, you're probably a friend of someone who was.
Earn Your Happy Ending: By building their own lives and becoming members of the "collective unconscious," Edensphere's characters made themselves and their world real enough to survive the Remmy's awakening.
Genre Savvy: Some very entertaining 4th Wall moments in the game.
During any Zombie Invasion, characters from a Near Earth universe generally pipe up with specialized Zombie Survival Tactics they learned via modern media. In 2010, this was primarily Above and Genius.
Upon being asked by Kurayami why he liked her, Smoke remarked: "What, you want some sappy monologue about being The One? Like hell you'd believe that coming from me anyway." Given the context of the rest of the log, it might also be considered a bit of lampshading.
Laser-Guided Amnesia: Everyone. People remember how to speak and function, they may remember things like the name of their homeworld and, say, that Disneyland exists, but they don't remember who they are, what they did, who their friends were, or anything of the sort. Memories of single scenes can be regained through memory crystals.
Otaku: Fugue/Remmy. He populated Edensphere with the characters he'd absorbed from fiction.
The Other Darrin: Sort of. If a character is canon updated or dropped and taken by someone else they are born with no memories of their life in the Sphere. They have a different dream and usually name themselves differently, too. The others very much do notice, though.
The big example is poor Neil Dylandy/Lockon Stratos. He's been born as Sniper, Range, and now Aim, and in every incarnation he's worked in the weapons stall. In two incarnations he's been involved with Bastet, but in the third she's decided not to bother.
Team Pet: For a while, Derrick lent couch space to Boss while telling his roommate that Boss was this. He wasn't sure if Boss was either thatstupid or an epic Troll. After a line was crossed, he kicked Boss out.
Your Universe or Mine?: In the end, characters were able to choose between staying in the Sphere, returning home, or exploring different worlds. (None of them mutually exclusive except for characters who died in their home universe—they mostly decided not to risk going home in case they couldn't come back.)
