There are cases, depending on the responsibilities outlined in the position contract, where some editors do both, but mneme is correct.Because most people don't know the different between an editor and a copyeditor.
Copyeditors edit for grammer, spelling, consistency, and continuity (and for game products, making sure that rules constructs actually follow the rules).
Editors set direction, manage most aspects of publishing beyond the author (including interacting with the author) and edit for content and publishability.
Copyeditors are frequently contractors.
Editors are usually management.
I say this as a guy who does the job of both an editor and copyeditor in the same magazine.
