I think is interesting in how similar yet different we all play. I seem to be a control freak. I have to know what all of my sims are doing always. Always making sure they are doing what I want them to do to achieve the goals I set and the ones from their opportunities.
I don't do the free will until they reach elder, or when the next generation has married and is working on their family. I think that a factor also is the income your family has, along with the type of job. With self-employment it can be less rigid as there is no schedule to get them up at a set time, bathed, have breakfast and be ready before the ride shows up.
Self emplolyed can sleep late, stay up late, work in their jammies or get dressed; it doesn't matter in that aspect. Also how the lifespans are set up; default? I feel trapped, really limited on how much fun my sims can have. Set as I have, with shorter and longer depending on stage, 2 babies, 10 toddler, 10 child, 20 teenager, 40 for YA and Adult and 20 for Elder has more time to work on my goals. More time to make money, have some fun, enjoy family later and able to work on having more money to move out of the small house my sims started in and generally have first child in.
Then, when enough money, move out into that nicer house with much more room to give each room and be able to add rooms with the extra yard space; a study, library, formal dining and breakfast area, small parlor type room at the entrance, family room, any others that I feel are important. Which varies for each of us what we want, how big, fancy and the styles, Victorian or modern, western or classical. Or even do we want to see that as another step to the nicer home, a medium size house that fits the needs and look to buy a larger, nicer home after more money is made.
Other factors that vary from player to player on what we see as important to our sim family; goals, wishes, rewards and other which can affect as we play. I guess that is what I find interesting, what we see as important, what we want from our game, our sims and even ourselves personally and in personality.
Sorry to ramble on, I just think of how we all play differently, my son is rigid, set a specific goal and when he reaches it that is end of the game. I am flexible, want to have freedom to change goals, play for what I see as fun, not a set goal, reach a certain level and that is the end of my game.
