I played SoMI not too long after it came out (I think - I was only young) on the Atari ST.
I was then completely oblivious to any sequel until my uncle provided me with a pirate (oh the irony) copy of CMI.
Then I bought the Bounty Pack, and played LeChuck's Revenge
Then I got EMI when it came out! I went to PC World especially
So, in answer to the question, 1, 3, 2, 4.
I've since aquired the amiga versions (and an amiga, which helps) of both the early MI games, and a couple of other gems to add to my collection which I played through quite recently, but generally I've played through all four roughly once a year each since having them.
And no, I'm not an EMI hater, just a Monkey Kombat hater lol
