The reason prices like that can be a problem is because they don't offer a meatier or sufficiently risky product for that money, they just have something popular and feel they can do it like Activision Blizzard has, or because they're being idiots like SE had been with DS pricing at times. Neither is the case here, we're getting a meaty RPG with a niche appeal, and looks to be about on par with the PS2 games we had to pay $50 for anyway. AND is likely on a more expensive, larger cartridge.
Don't forget that more often than not RPGs were the games we had to pay a premium for in the past, that only really changed on the PS1 and even on PS2 they were more likely to sell at $50 than others. I'm more than willing to pay $50 here, so long as they give proper localization treatment and don't do crap like SE demanding a premium price on Valkyrie Profile: Covenant of the Plume only to hack away the VA anyway.
Or hack out a major character building feature/the only really substantial change to the game over the NES version like they did with DQIVDS or sell the game piecemeal to disguise the fact that the game comes up to more than what other contemporary games cost without adding anything but a chapter release schedule to wait for like with The
