I did not notice the post on the Investors site when the game which has been shown as part of the pipeline for the first time was initially announced. There was not a pr release for it as far as I could find.
Funcom always refers to their PR posts as the full posts. Initial game announcements aren’t mentioned on the PR site by the looks of it. I understand this decision, but it is slightly inconvenient when this is called “complete” while the investors post includes the announcement. I also understand the latter, I don’t like seeing “announces new game” for all of them, there’s trends etc.

It is easier for newcomers to do so this way, than by going there and then to the editor. It is useful; say: to not have empty boxes lying around when you don’t need them (maybe a bad example).
