Current Projects
Girls life:

An in-depth life sim about living in Russia. Built in the quest soft player engine.

Trap quest:

A feminization/adventure game about being trapped in a VR game and trying to escape before being turned into a mindless bimbo. Built in the Inform 7 engine.

Student transfer: A community-sourced Visual novel made in ren'py. About an average high school student who either finds a book of magic or a reality bending remote.

Press switch by Skeigh:

One of the most influential visual novels in the transformation scene. A male high school student in an unhappy home situation finds a reality bending remote and has misadventures with it. Notable for its impressive scope, vision and darker themes were very influential. Made in ren'py and uses liberated art assets.

Student transfer:

The community's attempt to make a follow up to Press switch. It's a full on community project at this point, with people submitting their own scenarios or writing for the official scenarios. A high school student either finds a reality bending remote or a book of magic and goes on misadventures. Made in ren'py and uses liberated art assets.

Format: Life-sim
These are games often made in Twine that replicate to some degree the vision of Cursed! (Anonymousman, 2011). These are often mixed with feminization games. The core game play loop is about living out a daily routine and being transformed by that.

Newlife by splendidostrich:

A completely text based game, the player character is turned into a woman through mad science and has to live as a woman for a year while the machine to turn them back is built. The emphasis is on building a female character, then having turn by turn sex with randomly generated men characters. Although there is a heavy dress up element and job to go to.

Girl life – Community edition:

A community project to translate and then expand on a Russian made life sim. Extremely popular within the community due its depth and chracter development.

Magical camp by HLF:

One of the most popular games on the TFGS period. There are a number of games taking direct inspiration from it both in subject matter and style. Magical camp is about a young loser named Eric who winds up in a magical girl training camp and must act like magical girl Erica to fit in and avoid the psychopathic camp director. The game-play is like Persona in that action is split up into days and there is an emphasis on building relationships with your teammates in order to get buffs. The transformation is a slow feminization sequence as Erica absorbs magic to be a better magical girl.

Monline by Revilo:

A bad end heavy game (where a bad end is a transformation sequence that ends the game.) You play as someone trapped in a VR game full of transformative Monster girls and situations. You try to escape unchanged. A heavy emphasis on monster girls and anime pictures. Less copied but still very influential.

Format: CYOA games
The most common game in Twine is the Choose Your Own Adventure (CYOA) where there is very little gameplay but you just make a choice and read the result. There are a lot of these as the bar to making them is quite low, you just need to be able to write prose. Most of those are unfinished and are also often used to make life simulation games.

Lily's games:

Lily was an early twine developer who made dozens of projects of wildly different subject matter. "Into the dungeon" and "magical girl contest" were probably her most influential ones. The would just sort of shotgun out very evocative concepts even if they didn't always finish the games that had the concepts.

Devious world by Skooma:

CYOAs by their design feature a lot of choices and therefore often run into combinatorial explosion where too many choices makes the workload inhumanly large. Devious world leans into this having a huge variety of stories and endings, and even more unfinished content. Just about everything you can imagine exists in this game somewhere.

Fanucci's Amazing Pizza! by daviezwei:

A fun lighthearted game about being transformed into the perfect delivery person for a pizza place. The light-hearted tone, humor and emphasis on consent were very influential. Good art too.

Format: Turn-based adventure games
Similar to traditional (D&D style) RPGs, in which a character moves along a grid through a dungeon, undergoing physical transformation (and possibly mental) as the game progresses.

Trap quest by Aika:

The user plays a victim trapped in a VR game after winning a contest and signing a dodgy contract. The goal is to escape before being turned into a mindless bimbo. Heavy rouge-like elements and a steep difficult curve.

Feminization games
A wildly popular gaming genre, following a forced feminization narrative in which the protagonist adopts (willingly or otherwise) feminine dress and behavior.
