#19 The Game's triumph (WrestleMania 18)
Much like the situation seven years later, Triple H's "main event" title match was overshadowed by an earlier contest, this time The Rock vs. Hulk Hogan. Nevertheless, the crowd was surprisingly into this match. Mostly, it felt good to see Triple H get the title after he returned from his long injury hiatus. There was still a lot of goodwill there.
Unfortunately, the story was sullied by the divorce angle with Stephanie McMahon, which overshadowed Chris Jericho's own run as Undisputed Champion. That prevented the match and ending from being all that it could have been.
It helped that WrestleMania was a much shorter event back in those days, so the crowd wasn't completely tired by the end of it. If this angle had taken place in today's WWE, and after a long seven hours, I suspect the ending wouldn't have been as well-received as it was that night.
