Blizzard went on to create several other video games , including Warcraft sequels , the Diablo series , the StarCraft series , and in 2004 the massively multiplayer online role-playing game World of Warcraft.
Massively multiplayer online role-playing games -LRB- MMORPGs -RRB- are a combination of role-playing video games and massively multiplayer online games in which a very large number of players interact with one another within a virtual world.
As in all RPGs , the player assumes the role of a character -LRB- often in a fantasy world or science-fiction world -RRB- and takes control over many of that character 's actions.
