What kind of game is dune? What does it say? What is a red alert?

Dune magic castle came out very early (the earliest word game), even earlier than Warcraft 1 I played Dune 2 in the fourth grade of primary school (now 4 years older), and by 2000, Dune 2,000 came out. She told me that the human earth was destroyed by nuclear war and everyone emigrated. At that time, it was divided into three organizations, in my opinion, it was alliance, chamber of commerce and underworld organization. Every organization in the game is different from a single unit, and everything else is the same. . . . . .

The background of the red alert is the world war, and each country has its own characteristics. 1 generation, favorite Soviet Union, powerful tanks and electric towers, US Air Force, British Navy. At that time, there were more than 95,98 versions of DOS, but now the second generation is built on the basis of 1 generation, and each country has more characteristic arms, which is very interesting.
