Would love a time travel pack, with the option to go choose a futuristic world or a medieval world. Futuristic world would include hover cars, horse and carriage in medieval world, awesome futuristic/medieval build/buy and the chance to come back to warn your sims of future events. Maybe some butterfly effect, where if you do something while in the past, it will impact on your sim in the present. These might better fit game packs though than an ep. You could effectively put adapted versions of the Sim 3 Into the Future and the Sims Medieval into two different game packs.
