A tattered copy of this issue was one of the only Nintendo Powers my library had when I was a kid. I spent countless hours reading and re-reading it circa 1990. Ron Gilbert, creator of Maniac Mansion, is hanging out in The Cave's Steam chat room and I just had the chance to tell him. He said "Funny".
Never actually did play Maniac Mansion, but the sequel Day of the Tentacle is forever part of core reptilian Ian.
