: The big guys pull in high five figures to low six, the Star Wars comics pull
: in about double, but there's still plenty of company where Halo is on the
: list. That said, I do think that these ratings aren't really that great
: because as pointed out lots of people buy online or download, and it's
: hard to say how that skews it--I imagine a larger portion of the Halo
: fanbase would buy online rather than through your local comic shops. That
: said for comparison, the Halo Graphic Novel sold around 10,000 which was
: high for a one-shot, so X thousands doesn't seem categorically worse for
: Halo.

The first issue of Halo: Uprising netted 4,253. So I'd say it's safe to say Escalation (and Initiation, for that matter) are doing better.
