I always the PPV's that were different because you dont see those matches very much.
World War 3: 60 man battle royals with 3 seperate rings, it was one of my favorite PPV's when i was younger.
BattleBowl: Tag Matches but you has no idea who your partner would be. The teams were chosen by a lottery system. so you would see tag teams of people that would never wrestle together, like Sting and Sags... also Austin and Flair were a team, thats epic. The winner of the Tag Team matches advanced into a battle royal and the winner of the battle royal was the BattleBowl champ.
