I love rotational play - not all my saves are rotational but I do have a few.
1. When you begin your play what rules do you abide by (if any)?
I usually ensure that I switch families at about 6 AM (when most families are waking up). I make sure everyone is at home the home lot when I switch households. I have aging off except for my played household. I also create all the families and move them in to their houses before starting to play. I place seasons on 28 days when I'm playing rotationally. I sometimes have other rules but it depends on what type of game I feel like playing.
2. How many characters do you play and are they usually single..married...married with kids or are they direct family members (example ..mom dad and/or siblings.
For rotational play I usually start with married sims and usually start with somewhere between 6-8 families. I let them develop their careers, skills and relationships with the others for the first week or two before starting to have kids.
3. how long does this type of play hold your interest approximately? ( for example..a week...a month ...longer?)
A while - usually longer than a month. I do tend to take breaks from this style of play every so often but I always come back to it at some point.
4. Do you usually use NewCrest so you can create your own town or do you have a favorite neighborhood and why?
I pick different worlds depending on the story line I'm playing with. I've played in Willow Creek, Oasis Springs and Brindleton Bay so far. I usually do place new community lots from the gallery - but I also tend to put community lots in all the worlds because if I'm playing 8 families I like various different lots.
5. Would you say there is any draw backs to rotational play and if yes then what would those draw backs be?
Rotational doesn't always work the best if you are sending Sims to university. Sometimes I really get into a family story line and I don't want to rotate even though I still do because I want to keep the rotations the same.
6. other then using rotational play what type of simmer are you in game...for example ...do you prefer family related play....single sims over couples...do you prefer to begin as a teen in a family or something else.
I'm a family player so even when I play rotationally I'm usually playing families and then it is fun having all the kids grow up together and giving them different relationships (some are positive and some are negative). I usually start the Sims as young adults but I have started as teens before.
