I remember something like this being a topic for Mania. Basically you make a balanced (Can't be all main events) 8 match card using previous Summerslam matches. You must have a WWE, WHC, IC and Tag Title match on the card and you can't use any wrestler twice.
WWE Title Match: Stone Cold Steve Austin vs. The Undertaker
The Attitude Era and two of my favorite wrestlers of all-time. I still remember a lot of the promos for this match, and for me at the time it was tantamount to the Mega Powers colliding.
WHC Title Match: Randy Orton vs. Chris Benoit
This was the hardest to pick, there weren't many that I enjoyed of the ones I did are on other matches. I wasn't watching wrestling at the time but I remember randomly catching this match and being impressed by the story, didn't think Orton was going over and Benoit put him over in the end. There are some really horrible sounding WHC matches.
Intercontinental Title Match: Bret Hart vs. The British Bulldog
When I started watching i was a huge Hart mark. I went back as a kid and rented this on VHS and it's simply a classic match. It had a great story and it had a great payoff.
WWE Tag Titles: Legion Of Doom vs. The Nasty Boys
Tag titles were hard to select as well. I went with this one because LOD are one of my favorite tag teams and I don't really like the Nasty Boys at all so watching them getting their heads kicked in would be fun for me.
CM Punk vs. Brock Lesnar
Kinda cheating and there is a chance that the match could be a dud but I love the storyline so far, it's been good from top to bottom. A match that in itself has got me to buy the PPV.
Hulk Hogan vs. HBK
I actually love this match because of how controversial it is with all the behind the scenes stuff. And even when he is overselling HBK is still entertaining. The greatest of all time vs. Hulk Hogan.
Razor Ramon vs. Ted DiBiase
Great story for this one and cemented the face turn for Razor. All you need for a face turn back in those days is a worse heel and the Million Dollar Man was an all time great heel.
Edge/Sable vs. Marc Mero/Jacqueline
I'm a sucker for mystery partner matches and I remember at the time I was rooting for Edge cause I thought his gimmick was great and he was new and you weren't sure if he was going to get a push or not. Gotta get a woman on the card and doesn't hurt to watch Sable in her prime.
