9. Shane McMahon vs. Vince McMahon
Despite the fact that Shane O Mac was never traditionally trained as a wrestler, hes been involved in some fairly epic televised rivalries in his time. Perhaps his greatest rivalry though was with his own father, culminating in a Street Fight at Wrestlemania X-7. Sparked after Vinces apparent affair with Trish Stratus caused Linda McMahon to fall into a catatonic state, Shane challenged his father to the match-up in order to defend his mothers honour. It wasnt the longest rivalry in WWE history but it made for juicy drama; it was part pro-wrestling and part family drama. Some say that this was around the time the Attitude era came to a close; so maybe in WWE 13, this could feature towards the end of the Attitude storyline. But with the games announced roster including everyone of note in this feud (Vince, Shane and even Linda) its seems as likely well be playing through this storyline as it does with any other.
