I used to be a huge comic collecter a while ago (geez, 8 years now?). Way back when all the 2099 series were out was when I would read anything I could get my hands on. I've lapsed since, but I'm starting to pick it back up now, mainly with trade paperbacks so that I can get whole storylines without waiting or spending oodles of cash.
Can anyone recommend to me the series I absolutely MUST have or read while I'm getting back into it?
While we're at it, what are your favorite series or storylines of all time?
