This Ocarina of Time remake is brilliant in so many ways. Eiji Aonuma and the director Fujibyashi has spoken in the past after Tears of the Kingdom that the open air Zelda stuff is the future and they have no interest in going back to making new, original, traditional style Zelda games - the kind of games Ocarina of Time helped normalize.
This allows them to focus of course on the future of the franchise, the more popular direction for the series. Makes sense, but it upsets those that hate the new direction.
Enter, a from the ground of remake of Ocarina of Time. First, it tugs on all the nostalgia and the complaints about no more traditional Zelda games. Also hedges its bets for sales. They likely don't expect it to sell 20m copies.
But let's say they want it to sell 6m, but instead it sells 4m. Well, the game has a direct sequel that reuses assets before... in Majora's Mask - a quicker turn around game, that can then make up for the sales issues. Hedging your bets.
Takes care of those complaints, is almost no real sales risk, and allows your main team to focus on the next big seller. Everyone wins.
