Voice acting, compendium and 8th day don’t know if it added demons or skills. For me the 8th day alone was worth a re buy granted I didn’t play all the paths on the DS one but some are just way better for example Yuzu’s is one of the best imo.
[details=Spoiler]Get help from a stranger I guess is Loki to kill Beldr.
Managed to recruit Hero Midori.
Managed to shift Kaidou’s focus.
Managed to somehow help Mari into killing that vampire while failing the mission about 6 times.
Saved Kesuke’s dumb Lawful ass and got him back.
Saved Haru about 10 times.
Still trying to go for getting Haru, Mari that soldier chick, and Amane into the party.
