Boring and uninspired
3 for effort coding and developing this only. Didn't really make this as riveting as Motherload, though you tried to with the monetary rewards for missions to try to replace the random loot you occasionally found in Motherload.
Plus, unlike Motherload, there's nothing to really draw me back in. I've been playing Motherload for years and still can't get past a certain point in the overall story. In addition, most of the time I have no idea what I'm mining when I first encounter a new mineral, unlike Motherload.
The biggest thing lacking in this game is a concrete reason to return. For Motherload, it was the random radio transmissions. If you want higher ratings, change the game to include something like that, or some other reason to return.
