Yeah the original Secret Wars was a fun read..
I had the opposite experience in that I'd pretty much read only Spiderman and the Hulk at the time, (though I'd caught a couple of reprints of the original x-men) so this was my introduction to Wolverine, Colossus, Storm, Rogue etc..
It also gave me a deep abiding love of Victor Von Doom as THE Marvel villain, which pretty much survives in me to this day..(But then Shooter always wrote a fantastic Doom..He gave him some great scenes and dialogue in the 2nd Superman-Spiderman team up as well..)
