This is one of the first Gamepro magazines I remember getting:
I don't really remember much about it though, but I begged my parents for a subscription and they obliged. I still have that Mario 64 strategy guide somewhere (I used to rip them out and make books out of them).
Do you remember the issue where they tested the strength of all the different game controllers? I think it was N64, PS, and some other system (Dreamcast maybe?). I think the 64 won out overall. I remember the tests included things like dunking them in fish tanks and dumping Coke on them... maybe I imagined it, I dunno.
EDIT: I just found this retro mag site. If you wanna read all the pre 2000 issues, they're all available for download here: http://www.retromags.com/forums/files/c ... e__num__10
