I still believe the Matrix Online videogame had a lot potential, it just needed a better game loop, I think some new Matrix game taking ideas from games like Helldivers, GTA V and Cyberpunk could become a hit, where there are 2 parallel worlds, the Matrix and reality, and some things you do in one can help you in the other, e.g a way to discover from the matrix where the sentinels are in reality, the overall aim of the game would be to gain territory on "reality", and you would gain "exploits" that help you gain territory faster, meaning destroying robot bases and liberating human farms, plus recruiting some of them. On the monetization side the publisher can of course just do the popular thing and sell skins (that only show in the Matrix of course), for both cars and characters, maybe paint jobs for your ship would work fine too.
