I kinda petered out during generation 2, but I started doing a legacy where the game started with most packs disabled. I didn't bother disabling stuff packs (except pet stuff, since that's dependent on Cats & Dogs), and 3 of the 4 first GP's stayed on- Vampires off, but the other first 3 were definitely not worth a generation focusing on. Each new generation got a new pack switched back on, chosen with dice rolls. Game packs were paired up- if "x" is rolled, that represents these 2 GP's. The first dice roll gave Gen 2 Realm of Magic and Jungle Adventure. Gen 3 were still kids when I got distracted, but I had rolled for them and EP 1 was chosen- Get to Work.
