Metroid
1. Give Yacht Club Games the budget (I'd say 30M is safe enough) and a Development team of about 50 people;
2. Make them develop a 2.5D classic Metroidvania Metroid game with the controls of Super Metroid, make shure the third dimension is used rarely but use it when the character is moving towards a boss battle so that after the first battles they'll say "Oh, I've moved in the third dimension, I wonder if I'm going against a Boss or something important is about to happen", the game has to be set in an alternate timeline/after Fusion;
2.5 consider the possibility of a multiplayer mode, realize it only if works out properly;
3. Sell the game at 40$;
4. Give Monolith Soft/Hello Games the budget (50M+) and make them develop Metroid Prime 4 (I'd call it Metroid Prime Resurrection). The game has to include an Open World where you can challenge all of the Bosses in the order you chose just like BotW but only after defeating certain bosses you'll be able to fight them again in other areas in different forms (I.e. Meta Ridley). Of course this is a Metroid game, hence you won't be able to explore the whole world right off the bat, but every time you chose a path you'll have multiple options to chose from for what you have to do.;
4.5. Focus on a balanced multiplayer mode, make it a priority for the game;
5. Sell the game at 60$:
Series saved from oblivion.
