Branching Paths for Rails
Pokemon Snap is an on-rails game, meaning the Zero-One vehicle travels along the set path. A lot of fans wanted a sequel to allow the ability to travel freely on foot, but to me, that wouldn’t be a Snap game.
A good compromise, though, would be if the game gives you multiple branching paths you can take on the rails on each course.
In the first game, this wasn’t possible. The only thing close was that you could make an Electrode explode to open the path to a new course. However, there wasn’t a way to take multiple paths within the same course.
Branching paths would be a great new feature because it would add replayability to each course. For example, perhaps you could take a left turn instead of a right turn in certain parts of the courses to go into a different where new Pokemon can be found.
