I grabbed Yakuza 5 when I saw your post about it, but as far as I can tell it didn't actually replace Fat Princess.
Free Plus games I added just now:
Call of Juarez Bound in Blood (PS3).
Fat Princess (PS3).
Saints Row Gat out of Hell (PS4).
Furi (PS4).
Prince of Persia Revelations (PSP/Vita).
Oreshika Tainted Bloodlines (Vita).
