$40 is fine for these visual overhauls. Thats what they released Ratchet, SOTC, and Halo for. Same gameplay, just completely overhauled the visuals.Those changes are minor and should not warrant anything more than a $5 or $10 max as DLC. Add to tha visual overhaul and I'll give you $30. I can even understand £40, but asking $60 or $70 is downright criminal.
I think Nintendo with their $60 Links Awakening visual overhaul made them think they could get away with $60 releases. Only they now have to pretend every game is worth $70 on PS5 so they probably have no choice but to charge it that much. Anyone who has played real remakes like RE2, RE4, Mafia, FF7, and MGS Twin Snakes knows that there is a clear difference between asset flips (which is still a lot of work mind you) and complete remakes of systems, bosses, and levels.
Whats funny is that Nintendo charged $40 for their latest Metroid remake after charging $60 for a freaking remaster for Skyward Sword. Maybe they learned their lesson after the game didnt hit their sales target? Maybe Sony will do the same going forward with their Horizon remaster/remake.
