It was a remake of the best RTS game I knew, and also happened to be based on Dune.
Dune II set the stage for years to come, and Dune 2000 took all the elements that had been added to other games, and made the original play catch up. In theory.
The graphics got a touch up, and were better than the original, but not as good as they could have been for the time period that it was released. That said, the game ran smoothly on a decent PC.
It was a remake, and nothing more. No new elements, no new story, no new anything. You could now group your units. Yippee. I was horribly ashamed to have this game on my machine.
The Bottom Line
This is the game that shouldn't have been. It took the name Dune II had created for itself, and tried to survive on it. I'd call this game Dune II with a little tinsel, but not enough to justify buying a new game.
