I know this is a little late, but I had to review Thorium Wars.

Ok, I give this game a 8.5 out of 10. Why, there is no multiplayer and it can be a little hard at times. It also has that price, which is pretty reasonable for how great the game is.
RATINGS:
MUSIC: 9/10
GAMEPLAY: 8/10
CONTROLS: 10/10

conclusion:
It is a really great game! The only terrible thing is the lack of wi-fi.
