For me Dune gives a feeling of being a kid in a candy shop again. It’s the prequel of the command and conquer series (most know for red alert) by Westwood studios. 
As a young kid it was the first game I couldn’t stop playing against ever more and stronger computer opponents. 
The storyline in the game with the different houses is also quite nice. 
For me it goes back to this computer game I really loved.
