They've added a lot of old house shows in the Old School section. Mainly shyt from the '70s though
Why not add more MSG shows from the 80s and 90s?
They stopped taping them after 1992, Prime Time Wrestling is almost entirely cut up house show matches from that period, and the cards/matches were nearly identical for months at a time that it doesn't make much sense to essentially upload them over and over again. Back in the 24/7 days, I saw a Blue Blazer vs Barry Horowitz match that was exactly the same in 4 different arenas from the same 3-4 months.
