A lot of it reads as lazy DLC meant to satisfy investors that want “value-adds” without taking a lot of development time. I’d imagine only obsessive fans (admittedly, there are many) would be considering them.

But the fact that it’s a remake of a 20 year old game doesn’t seem like it would affect the value. For reference, the old one was top down with prerendered chibi sprites. The new one is fully 3D with voice acting. It’s a pretty sizable change in appearance, even how the combat functions. $60 is probably normal, though it makes sense that for anyone unsure about it, either play the demo or just wait for it to go on sale.
