Starcraft is an RTS game made in 1998 with its expansion made in 1999, you should look it up if u want to know about it. Their are 3 races, Terrians(Humans), Zerg, and Protoss, each team had different units. unlike some games today none of the units where completely alike, A Hyradlisk(moderate speed, ranged) can kill 2 marines, but marines(moderate, ranged, can be upgraded with stim packs which make him run and shoot faster but take some of his health) could get range upgrade so the hydra wouldn't be in range to kill them, but most Zerg units can burrow(hide) so you would burrow it let it heal itself and then unburrow and attack, or you burrow a group of Hydras and then send a Zergling(fast, melee) or 2 in and drag the marines into a trap, but the Terrian player might have used a scanner and seen your burrowed units and set up Seige Tanks(Tanks that can deploy into Artillery) and wait for them to unburrow and blow them up. you get the idea, no 2 different units units are alike. I know, I talk too much. I have the game and its expansion, and going to freak out because they made a Starcraft 2
