Hyphen for Editions or reprint series only. All of those should have a colon.
...Weird then considering these games are literally remastered versions of the original games with updated artwork released on steam. The steam webpage even has the games listed with a hyphen, yet it keeps getting rejected by whomever. I have editing OCD. I wouldn't be requesting these changes if it wasn't obviously borked.
Chapter 5 on either the wish list or collection page is first, where as Chapter 1 is last if you have all five on your personal collection. So it looks like this:
Higurashi When They Cry Hou - Ch. 5 Meakashi
Higurashi When They Cry Hou - Ch.2 Watanagashi
Higurashi When They Cry Hou - Ch.3 Tatarigoroshi
Higurashi When They Cry Hou - Ch.4 Himatsubushi
Higurashi When They Cry Hou: Ch.1 Onikakushi
Whoever is rejecting the edits, if they aren't, needs to take a look at the naming convention of the whole series (
ALL FIVE!) rather than just the individual entries.
