My favorite kind of PT is any one where I have the option to talk about my player as a person or character, so I lean towards the back story type of tasks. The simulation itself is just numbers, and it's cool to plug the numbers in and get results, but there are only so many combinations you can really make out of all those numbers, and to me the most interesting players are the ones people have gone to the effort of fleshing out and making them feel like real people with real back stories. These are also the most fun for me to write, because I have put a lot of creative energy into trying to make my player feel like a character and not just a set of stats. I know other folks are in other leagues as well and I totally understand not everybody is into the storyline sort of stuff, but I always love it when that's an option, and that's a lot more fun for me than having to go look up old stats from before I joined the site and such.
