I think so.Also, dream matches most of the time are big matches that could be done, if promotions put their differences aside for the fans.
I could name a few dream matches that should happen, that we want to happen, and wont happen due to promotions being by for themselves.
1-Sting vs Undertaker
2-Shawn Michaels vs AJ Styles
3-AJ Styles vs Chris Jericho
4-Abyss vs Kane(1000 tacks/Inferno)
5-Beer Money vs The Gatecrashers vs MCMGs vs The Hart Dynasty
6-Kurt Angle vs John Cena-This has happened once, but this match would bring the arena down.John Cena would kick out of 3 Angle Slams and Kurt Angle would kick out of 3 Attitude Adjustments.The winner, up to you.
7-John Cena vs Shawn Michaels vs Undertaker
8-Rhyno vs Edge
9-Samoa Joe vs HHH
10-Samoa Joe vs Undertaker
11-Randy Orton vs Stone Cold
-------------
Why not do divas/knockouts?
1-Melina vs Angelina Love
2-Melina vs Gail Kim
3-Melina vs Natalya
4-Natalya vs Beth Phoenix
5-Natalya vs Gail Kim
6-Natalya vs Angelina Love
7-Gail Kim vs Beth Phoenix
8-Beth Phoenix vs Angelina Love
--------
The list could go to retired/dead/active.I dont feel like doing that far though.It could expand outside of TNA/WWE as well.
