7. Undertaker vs. Kane
If I were to include the Undertaker vs. Kane storyline from late 97/early 98 in WWE 13, I would start it with the video package of Paul Bearer telling Undertaker that Kane was still alive. Then, as the first match in the storyline, players would take control of the Undertaker in his Bad Blood Hell in a Cell match against Shawn Michaels in which Kane interfered. Players would take control of Kane as he tried to get the Undertaker to have a match with him despite Undertaker refusing to ever face his brother. The original storyline ran from Bad Blood in September, to them finally facing off in a match at WrestleMania 14. After a few weeks of minor matches building the story, we could then move onto the Undertakers Casket Match with Shawn Michaels in which Kane interfered again and set the casket on fire. Finally, this would lead through No Way Out where Kane fought Vader and ultimately into their showdown at WrestleMania 14. Depending on how long the storyline needed to be, it could even be extended a month forward to recreate their Unforgiven Inferno Match.
