Yea, I was just about to mention that.
Chi-Town Rumble has the first 1989 Flair/Steamboat match, a good Luger/Windham US title match, and an entertaining Loser Leaves town six-man with both Midnight Express teams. Plus the two major singles titles changed hands.
WrestleWar is really about the main event but there the US and World singles titles change hands again.
GAB has Flair/Funk, Sting/Muta, Luger/Steamboat, and War Games all of which are good (or better) matches.
WrestleWar is the weak link in that chain but the great main event might be enough to hold it up as a "great" PPV. At least everything else on that card was kept short.
WrestleWar had the main, which over time has become a Love/Hate type of match (relative to the earlier two big Flair-Steamer matches still being fully Loved). It was hurt by a supporting card that just didn't take off. At the time, Hayes-Luger was surprisingly entertaining... but I wonder how much of that was the surprise of Lex losing. Even if the match doesn't hold up (16+ minutes from those two is a lot of time given Lex was in face mode), I'd say it was at the very least a decent supporting match for the booking and title change and adding to the aura. But the rest... the final two title matches were in an anti-climactic spot, and neither delivered. The undercard was mediocre. It ends up being a one match card.
It's too bad one can sub in Starcade '88, which had the strong main with Flair-Lex, a wildly fun Steiner-Rotundo TV title change, what I recall as a solid Barry vs Bam Bam US Title match, and I want to say a solid MX vs OMX match.
The Fantastics vs Doc and Sullivan opener was also very good.
