I've noticed recently that some Japanese games with both English and Japanese VO tend to cater to the English VO in terms of lip sync. Asura's Wrath and Killer is Dead are two I can think of currently but I'm sure there's more. While I do understand that perhaps these games were made for a western audience to begin with (?) it's a bit peculiar to see broken lip sync in a Japanese game with Japanese VO.
Or then again, it may just be low production values and/or developers not caring anymore.
