I bought Amiga Format the most. Only missed the first 3 issues if I recall. Still have virtually a complete set with all coverdisks and CDs.
I also bought the US magazine Amiga World for about two years until it folded.
I bought Amiga User International until it stopped also.
I then bought AmigaActive until it converted into a digital media magazine (I think that only lasted one issue).
Periodically if I liked the coverdisk, I bought Amiga Computing, Amiga Shopper, Amiga Power, The One, various others who's names I forget.
Oh, and I bought every issue of CD32 gamer despite not having a CD32! (I planned to get one but never did)
I still have every one of these magazines, and occasionally pick one out to read. They should bring happy memories, but sadly I feel a great sense of mourning sometimes.
