SteamWorld Dig 2 is basically just a bigger SteamWorld Dig 1. I didn't feel that any of the differences between the two were monumental. This one has a much bigger focus on the story, which kind of makes sense because the ending of 1 was a little weird from what I remember. The music is good, but nothing crazy. The gameplay and visuals remain mostly identical to the first game. The map is much larger, but it felt as if they wanted it bigger just to say it was bigger. Not much purpose to that for the most part, I thought. Still, SteamWorld Dig 1 was a good game so 2 being mostly identical isn't even a bad thing. Good job.
