How many notable stories like this are there?
I've been on an '80s binge and I've read three so far during this time. One was Secret Wars (including Spidey's iconic fight with the X-Men), one was Marvel Team-Up Annual #6 (pairing him with the both the New Mutants and Cloak & Dagger), and one was The Amazing Spider-Man #282 (a crossover with X-Factor, then the reunion of the O5 X-Men).
I'm kind of curious about how many good crossovers there are between them. Any recommendations?
