In my game, I have taken inspiration from various other RP games, role players, and other creators' gameplay styles.
Nothing that I do is something no one else has not ever done, so I just want to clarify that I am in no way saying these ideas are solely mine. I just want to share my own specific style and mix of things many people have been doing for a long time :)
You can pick, choose, and mix up gameplay rules and styles from whoever and however many playstyles you like. All that matters is that you are having fun and feeling inspired by your game!
Rotational Gameplay
Firstly I like the rotational gameplay that a lot of Sims 2 and Sims 3 players enjoy.
Check out PleasantSims' site as it seems to be the best resource I can find for other people who are also interested in Rotational Sims gameplay so please check her site out for a super in-depth look at how she does things.
I don't follow her style completely and you might like some aspects of that version more than mine :)
Story Focused
I enjoy playing with story and drama as the main focus of my game.
You can accomplish this from various methods, but the main elements I like to focus on are:
Wishes Focus (I look at these somewhat like Wants/Fears in Sims 2)
Story Progression Aspect of Sims 3
Mods for additional gameplay mechanics
Random Roll Focus.
Random Roll Clients
I really enjoy using DDDice as it is super aesthetically pleasing and brings in that true RP feel when making roles like you would for D&D.
For specific rolls that may need a non-traditional number set I also use RollaDice
I enjoy focusing on the story progression aspect of the Sims 3, combining that with focusing on their wishes a little more than some people may and spicing things up with rolling randomly for the outcome of certain scenarios.
I like the authenticity your Sims' have when playing this way. It makes it so each playthrough will be different as you're not the one leading the charge on all the decisions based on what YOU want.
I go into specific scenarios where I use random rolls in my game later on this page.
