I wish I had more time to make a post which best illustrates just why
Mega Man is a great comic book to get into, and hopefully this post will at least serve as an impetus for that. If nothing else, I included what tags I could to make looking for previous posts easier.
But the main thing is to spread word that ComiXology is having a line-wide sale on Archie comics, of which Mega Man is one, and between the 50% discount and the already-low price of $1.99 USD per issue, you can basically get the entire run for $55. Less, if you decide to trim the Sonic crossover stuff out (incidentally, the Sonic stuff is on sale, too, and worth reading).
The trades have stalled following the hiatus, leaving that option for reading the series in doubt, so that makes this the best way to get caught up. And hey, maybe buying these will show enough support that Archie decides to take the book off "hiatus."
You can find further details here
Do note that the single issues are the better value over the trades which are available, unless you really
like variant covers (which can be found online anyway) and bonus content.
