I guess I'll talk about the game I'm currently playing in the wider sense of the price tags its series carries. Atelier meruru is the 13th game in the Atelier series, and the 3rd game on PS3. All of those games (and damn near every game in the series before it) are pretty easily found for 300 to 800 yen ($3 to $8), *except* for when you get to the first game released cross-generationally. Atelier Sophie is the first game on PS4 as well as PS3, and that game is absolutely impossible to find for less than 1500 yen here. Just that huge jump in price (for a game that, as far as I understand it, wasn't particularly popular or anything), is very very weird to me O_o.
I mean I guess to a point it's just part of the general trend of PS4 games generally being quite a bit more expensive overall, but that doesn't go as far to explain why even the PS3 version is so expensive. Like, the price differences can't be down to "well more people have a PS4 than a PS3 these days", because if that was the case, then why would both the PS3 *and* the PS4 versions be more expensive than all their other PS3 counterparts (granted the PS4 version is significantly more expensive than the PS3 version, but still). Very odd O_o
