(There's some spelling errors)
Blizzard games are the standard by which I measure other RTS games. The ones I've played include; Warcraft II; tides of Darkness Starcraft Starcraft; Brood war (expansion pack) Warcraft III; Reign of Chaos Warcraft III; Frozen Throne (Expansion Pack)
Now, Warcraft II didn't really have a story, it had a prologue to each level but the story was always basically "We're going here and we're killing these people". Starcraft, on the other hand, had a very interesting story, which is maybe more engaging than a movie because you're actually acting in it. It had allot of political and religious themes in it.
Warcraft III and the expansion pack continues this. Prince Arthas changes as you play him. As a character. You find yourself wondering, "What are we fighting for, again?" because his motives keep becoming more extreme, and he seems to forget what he was fight for in the first place, not unlike George W. Bush. Ultimately... (No, I won't tell you)
ORCS/HOARD;
Most Orcs were born on Azaroth, but are technically native to another dimension. The Hoard is mainly made up of Orcs, but also includes Trolls, Ogres and Taurens. Orcs are green guys with huge muscles, tusks, pointy ears and ugly faces. Orcs have their own unique accent and language. Trolls, contrary to most depictions, are skinny, big-nosed, tusked, have Mohawk haircuts and speak in Jamacan accents. ogres are big dumb things with two heads, one with one eye and one horn, and one with two eyes and no horns. Taurens are basically minotaurs. Taurens, unlike the rest of the Hoard, are native to Kalimndor, not Azaroth
Humans/Aliance;
The Aliance is native to Azaroth. The Aliance also includes Dwarfs and Elves. Like Orcs, Humans must build gold mines, gather wood and build buildings in order to make more units.
UNDEAD/SCOURGE;
The Orcs and the Humans fled from Azaroth to escape the Scourge. The Scourge is mainly made up of various undead creatures; zombies, ghouls, banshees, death knights, ghosts, skeletons, necromancers, undead giant spiders, etc. It also has Demons from the Burning Legion.
The Except for Ziggurat and Haunted Goldmine, all Undead buildings must be built Blight, which is basically this black slime-like stuff that spreads out from Ziggurats and other buildings. This idea was also ripped off in one of the lord of the Rings RTS's where the Orcs can only build things on "Cursed Earth".
While the other races are limited to 100 units, Necromancers have the ability to turn any corps into a Skeleton, which can bring the actual number of units well over 200. Howevere, skeletons tend to disintegrate eventually.
NIGHT ELVES
Night Elves are native to Kalinda. Night Elves are nocturnal, have blue hair and purple skin. The Mostly female warriors, because the females have the ability to turn invisible at night when standing perfectly still. however, there are also males called "Druids with the ability to turn themselves into bears or birds, or bring trees to life (depending on particular type of Druid) There are also "Dryads", female creatures, basically a cross between a Night Elf, a Deer and a Centaur, with green hair. There's even a Night Elf God with the same description only male. the night Elf buildings are all sentient trees, like Treebeard. Should the need arise they can all uproot themselves and move to a new location, or even attack things. The workers of the Night Elves are glowing spirits called "Whisps". When gathering wood, Whisps are the only things that can gather wood without damaging the tree.
NAGA
Naga are native to the sea off the coast of Kalimdoor. Naga are a race that evolved from Night elves, their back story is not unlike Atlantis. Naga are creatures from Indian mythology; basically a cross between a Night Elf, a mermaid and a Snake. Their army also includes various weird marine creatures, including frog-like creatures and giant turtles.
