Starcraft - A classic strategy games

I play Starcraft now a bit longer, it came in 1997 to the market. Meanwhile, there is a legend among the strategy games. It's about 3 nations build one or more bases in space with one and then to fight the enemy.
Starcraft is not graphically highly sophisticated, but simple but challenging in play. So overall a game that I can recommend to anyone.
In the Brood War expansion, there is for every nation new units, but you can only play with the basic Starcraft.
