Bigs: I was wrong... and it DID
All the extra new DLC is available for Re;Birth 1-3 - and GOGs release of VIIR is up to date AFIAK
When I read your post a year ago, I remember getting really depressed thinking the DLC's wouldn't come... But I've never lost hope for some reason, and here we are. I understand why you said that, since lots of games were somehow abandoned here on GOG, still waiting for the updates available on other places. I'm so happy IFFY and Compa didn't forgot about us XD
I'm still hoping IF releases Original Megadimension VII, Nep RPG, Cyberdimension, and maybe other games (Death End Re;Quest in example) here. Who knows, maybe IF has some surprises for us this year too (or maybe I'm just getting my hopes up a bit much... :P)
