And you still did not read the OP. But I know, it is too much work...
Only one game. Not sure what you mean with "first", because in chronological order, it would not be the first game.
The first game is the first game. Even if a prequel comes out, the one that was released first is still the first.
Unless you are Starwars, I guess, and you start on episode 4, but nobody would be stupid enough to do that.
And no, the OP isn't clear about what the game contains, otherwise I wouldn't have had to ask
twice.
The OP describes it as a
full remake, but then it says "Of [Japanese name for both the first game in the series, and the informal name of the series as a whole]
That's why I asked.
Packaging the full series together into a single product is what they did with Country Girl Keiko, isn't it?
