This post is coming from a few different sources. First, I was reading a thread on OMAC and a poster (apologies for not referencing) had mentioned that some of the nu52 comics (I think Vibe for certain was mentioned) were possibly intended for a limited type series, to tell a story that led to something else, but not necessarily an ongoing. I also recall in the old CBR continuity, reading a thread where someone sang the praises of mini/limited series' and how they could be used more effectively in the nu52 DC. Use those as starting points, rather than putting characters in ongoings that seem destined to fail.
I will also preface my questions by saying (outside of an event where it is the main title -- i.e. Forever Evil) that I've generally been a bit of an ongoing-snob, where I really didn't think minis or non-event limited series were for me. I have had similar snobbery in other things (like length of books or music, as if that trumps a good song or story).
1) What are the challenges in a mini/limited series for DC? Are sales inheritently down for an admitted mini as opposed to an ongoing (even if the latter has an intended length, just not stated publicly)?
2) If one really takes off, how hard is it to make into an ongoing? Is it something where you lose some of the steam between when the mini was released and an ongoing can be published?
3) What is the upside to doing more minis/limiteds? (I tend to think you can introduce new characters, etc. and tell the stories you might not otherwise, without being committed to an extended ongoing series).
Anything else you care to address with regards to minis or limiteds is also fine by me.
Thanks in advance for your replies!
