I think part of the next phase is to force the companies to list a minimum supported life span, I think the average length a game is supported for now days is around two years, so if the game isn’t kept alive the minimum listed time you get a refund but if the life span of the game is listed too short then people will be less likely to spend money on it
Not sure if it would be puzzly enough but if the player can wonder the halls or get escorted through them having part of the knight’s efficiency based on how well you mapped out the area you send as a note plus you could try to find info on guard rotations or over hear about other things that could help the knight
