The graphically superior sequel to Command & Conquer, Tiberian Sun keeps the original gameplay mostly intact, while adding some intriguing twists. Your goal is to collect resources with your harvesters, outproduce your opponents, and use your troops to destroy them without mercy. New special units include ones that can dig like moles and pop up inside the enemy base. Don't worry too much about the two-dimensional sprites and the mere 800x600 max resolution: the game looks surprisingly good for a late-1990s production. It sounds pretty good, too, mixing techno music with arcade bloops and blams. The demo includes several introductory missions, whose difficulty you can adjust for added replay value. Tiberian Sun is a long way from state of the art, but real-time-strategy buffs will get a kick out of revisiting this classic series.
