3. Metal Gear Solid: Peace Walker
Peace Walker is a great game, and when you think about it probably the shortest one in the whole Metal Gear series. So, you might be wondering why I'm choosing this one over, I don't know, let's say Guns of the Patriots. That's because of the whole "Mother Base" mechanic of the game. Since a big portion of the game happens in the jungle, the first season might be centered around him fighting in Costa Rica. The second season might be centered on Big Boss trying to maintain MSF, while still dealing with Zardonof, and the developing of the Metal Gear Zeke. It gives the opportunity to show different stories or missions that involve the rest of the team in Mother Base. Maybe doing some episodes centered around other members of the group, expanding upon the existing storyline. And if we consider the end of the game, this can be a good way to develop the rest of the story. While we're at it, it could be really interesting if they end up doing this one as an animated series, since that's how the game's cutscenes are shown. And besides, I think it would be really good to see an animated show aimed at adults that doesn't have any dick jokes in it and actually deals with some serious subjects that very few shows have explored.
