Grim Fandango Remastered is the same game, puzzles and plot as the original release. Manny is a travel agent for the recently deceased. His job is to collect the souls and try to sell them up to faster modes of transportation to their final journey. While Manny was a top-notch salesman early in his career, he finds it hard to get clients that can afford the accommodations that will help speed him along his own journey through the afterlife.
The story actually spans four years, each segment starting on the Day of the Dead. When we first meet Manny, his career is in a downward spiral, but before the first act is done, he will find himself in deeper water and looking for a new job.
Manny's main drive is to find and help the wronged Meche, Manny's last client who should have been sent on an express trip to the Ninth Underworld, but was instead cheated and was sent on the four-year long journey without help. As Manny continues to follow and help Meche, he will uncover a deeper and more sinister plot than he did when he had to leave the Department of Death, and he will have to work hard to not only help Meche get where she deserves, but also help save a friend's life.
For the most part, the game's story is linear, but there are times when you can choose which order you want to solve certain puzzles. For instance, you are given a series of tasks by a local underground movement. While you can't progress in the overall story until all tasks are finished, you can tackle those tasks in any way you wish. Grim Fandango was by no means the first game to do this, heck Secrets of Monkey Island let you choose the order to some degree, but I remember feeling like Grim Fandango had a lot more opportunities to choose these paths than many other adventure games before it.
The Remastered version also adds Developer Commentary. If you have this feature turned on, then there are times during gameplay that an icon will appear at the top. When activated, you will hear Project Leader Tim Schafer, Lead Artist Peter Tsaykel, Lead Programmer Bret Mogilefsky, the man behind the music Peter McConnell and the rest of the development team, talking about the scene in front of the player. While you can adjust the audio of the commentary track, you won't really be able to make out both the commentary and the game, so as you might expect, it's best to save this feature for your second playthrough. The special features for this game also include concept art galleries and the ability to watch all of the cutscenes and read through the transcripts of the dialogue (as you unlock them by playing through the game).
