Same! Dig 2 was sooooo good. And there aren't many like it really. Searching for all the powerups, making notes about spots on the map. Loved it. Dig 3 would be an instant purchase for me, I hope they get around to it next after Build.

I would have been pretty close to perfectly satisfied just adding an "endless mode" DLC that randomized areas and did something to make power up progression feel bigger. I used to play the hell out of the browser mining game motherlode and this is the first example of mining feeling kind of similar that I can think of.

It is quite a bit different, but as far as games that scratch the "mining" itch, I found this to be really fun -
