Mankind vs Undertaker, Hell in a Cell, Pittsburgh.
This was at a King of the Ring PPV - not Royal Rumble.
OP asked for "epic matches" not just Rumbles. I couldn't remember the event, but I thought that I gave enough info for OP to find it on the network, thnks for the added detail though.
You're right - I misread it. Sorry about that.
Definitely one of the all-time greats!
That was from summer 1998. ECW's Heat Wave '98 was from around the same time period and that was an EXCELLENT PPV:
-Masato Tanaka vs Mike Awesome
-RVD & Sabu vs Hayabusa & Shinzaki
-Dreamer, Sandman, & Spike Dudley vs Bubba Ray, D-Von, & Big Dick (RIP) Dudley
