#3 Should make a comeback - Cyber Sunday
Although it is allegedly rigged, Cyber Sunday was a really good gimmicky PPV. In this age where everyone has access to the Internet, and WWE Network is on a rapid rise, Cyber Sunday would have been a perfect PPV to have.
In case you don't know, Cyber Sunday was a PPV where fans were allowed to vote, choosing stipulations or challengers for a world title. The flexibility and potential of this PPV were incredible.
