First-time poster here. I've played TiTS on and off for about as long as the game has existed, and I've had some ideas on things I'd like to see added, and would even be willing to take a crack at adding them myself. (If there's a FAQ I missed on what the submission review/process is, I'd appreciate any links. I did read the doc linked from the main site on writing details.)
One (more vague) idea I had is a branch off of interactions with Beth Carver. Maybe where, in attempting to convince Beth to free Del, Steele annoys her to the point that she tricks Steele into going through a process of becoming just like Del. It's clear that this is a trick, and the player can back out at multiple stages, but if they want, they can keep going all the way until a bad end.
The other I had is for a high-end club that the player can visit where the staff (servers, dancers, etc.) all move with a showy, clockwork motion. This is because the staff have all been trained/converted into clockwork doll versions of themselves, and start every shift with a key wound in a slot in their backs. The player can visit the club as a patron through the front door, but if they go through the employee entrance in the back, they can go through "employee orientation" that involves a VR "training" and the addition of a keyhole in their back. If they decide to start a shift, they submit to being "wound", which both makes them feel really good, and causes them to just move on clockwork autopilot for their shift as either a server or dancer, encountering customers, and the like. There's risk to doing it too much/too often, but the return is a good chunk of change per shift.
Sorry if that's a lot of rambling. Again, this is my first post, so if this is the wrong thread for any of this discussion, I apologize.
