The Gift Reloaded. Honestly. The game has legit antagonists, and an interesting story. Not to mention it is a fairly good Harem game.
To add fuel to the fire, it began to build a solid gameplay system beyond simply moving rooms and/or talking to girls in random rooms at specific times. It began to adopt an interesting management system into the core gameplay/story without needing to rely on prostitution/brothels to do so.
The game had a lot of promise and a strong following. The issue being that the dev is untrustworthy. Even if he returned there is no guarantee that he would follow the same development path. In all likelihood it would be revamped for the third time and take a more undesirable direction.
As for someone else taking over development, While someone could in theory do it, it would never be decent. Some people have tried doing this in the past for other games. They never work out, never get the attention it deserves and always ends with a flop. Why bother hoping for someone else to do such a project? Not to mention the questionable legality of such a project. Instead, I would much rather see someone make a different game, but take heavy inspiration from the game and make something better and more cohesive from the beginning rather than shift focus like The Gift did.
