What do you use to tell stories for your Sims?

Most of the 'stories' are in my head. But I started doing machinima way back in TS1. I fine tuned that in TS2. I still use MS' Movie Maker (original) to put together the pictures and videos. I have tried many other type video editors but I found that is the best one as 'free' software to use. I actually like editing videos and pictures to make up a story more than actually telling what happened in the game. I enjoy the editing most of all.
