Besides the character skin and the fact he was this girl's father, was it just the same game? I often get the impression people refer to Gestalt & Replicant as 2 different games.
From what I know, the protagonist should be the only difference.
(besides obviously the dialogues with it)
[I didn't have the opportunity to play Replicant, I played Gestalt, because Replicant was always only an exclusive for the Japanese market]
For this reason, this Remastered represents the first real landing on the world market of this version.
