Largest outdoor crowd would EASILY have to be for the NJPW (with some WCW guys) show in Pyongyang, N. Korea. You could arguably give WCW some credit for it --- but it'd be a stretch. Don't know EXACT numbers, but both days topped 100,000 fans.

Considering Flair ME'd it against Inoki in a dream match, WCW deserves SOME credit.
And a number of WCW guys were involved in the mid-uppercard as well. The Flair-Inoki show drew something like 175,000 fans, the largest wrestling crowd ever. Yeah, WCW definitly deserves some credit for that.
