I've already gave my definition at least twice. Games that require points, money, or some other form of keeping score to progress. Like a road block of having to purchase something for an LI to progress their story that costs an amount of money that you have to earn. Or sandboxes where people are on a schedule. I.E. Specific conversations that can only happen on a specific day of the week in the afternoon in that particular room. Sandboxes are things that require specific requirements of some sort to progress. Games like Milfy City have none of that, but still allow you to choose your path by letting you go to Caroline's room instead of your mothers. I.E. free roam instead of requirements to progress.
