So far, have you enjoyed EPs, GPs, or SPs most?

It's been Game Packs, hands down for me since Vampires came out. That's still my #1 favorite. I also love Realm of Magic, Jungle Adventure, Journey to Batuu and StrangerVille. Most of these I would rate above most EPs because they have a really tight, consistent theme that is done in great detail and brings good gameplay. I wish EPs were done that well. But I think they're getting better.
