It is important to note that if you aren't running on English Locale ADRIFT version 4.0 will not work. One helpful feature that ADRIFT has is that it includes a map for most games so you don't need to memorise routes. You can download all the runners here: ADRIFT

Update 2014: The game has a fair amount of content, but the game is buggy and the gameplay is still very unpolished, and you may find yourself literally telling your character to watch TV over and over to pass the time until you can go to work for a paycheck, because you can't afford to do anything else. However, as a life simulator, playing a person trying to develop your identity, pay the bills, build relationships, and strive to balance your funds between fun uses and practical uses, the game is actually fairly successful, with the occasional porn scene just for kicks.

The largest AIF Twine game by far and perhaps one of the largest text-based games ever.
A gender-bender life simulator that starts the player off in the role of Marcus, an effeminate boy with a stunted sexual development, who is offered to be turned into a woman by the mysterious Coleman Institute... or can try and make it on his own. The game's writing is great, the game is quite lengthy despite one entire section still in development and, thanks to a HUGE amount of different story branches (one sub-branch for each of the three sibling, one each for going to Coleman or not, one for which college you go to [or not] - multiply those with each other), there's a lot of replay value and content, even if playing a transvestite is not your cup of tea.
