On further investigation it looks as though the "Ludomusicology" page was merged into "Video game music" by a new page reviewer, because the page quality wasn't great (minimal referencing, un-encyclopaedic language, etc.). Should be entirely possible to set it up again, or a dedicated "Video game music studies" page (not that I really want to get into that particular terminology debate), as long as the quality is good enough. Which would require a concerted effort. I'm learning a bit about wiki editing (sometimes it's just too hard to let bad grammar slide) so I'm happy to help. Think I'll put a post over on SSSMG as well.
