The first time I read through the Marvel G1 comics, I read EVERYTHING the hard way, on purpose.
First I read Marvel U.S. issues 1-80, along with the first G.I. Joe crossover, the Headmasters mini, and the Movie adaptation (even though it's out of continuity) between certain issues.
Then I read the five G.I. Joe issues that led up to Marvel G2, and then read all 12 issues of the G2 comics. Then Alignment, and finally "The Last Days of Optimus Prime".
Following all that, I went back to read all of the Marvel UK stuff,
including the reprints of the U.S. issues that I had already read. So yes, I reread all of the above pre-G2 U.S. in my UK reading.
I read issues 1-332, then I went back and read all of the annuals (only recognizing then that some of the annuals' stories were part of the main comics storyline, which I had to mentally insert into the proper placements of what all I had already read before). After that, I read the five UK G2 issues that were published by Fleetway, and then read the UK G2 annual (which is itself another separate continuity from all other G2 fiction).
I don't recommend this to everyone. It's just what I chose to do.
As for a list, here's
another one that was based on the one Scotty linked to above. The person who made it is current making additional updates to it.
