Besides the first-person shooter (FPS) genre of games on the PC today, what is another group that is unique to the PC? Real-Time Strategy (RTS) games are hard to emulate on a console but a strong presence on the PC. Games like the Command & Conquer series and Blizzard's WarCraft and StarCraft games define the genre. Build a base, collect resources (usually gold or something of the sort), build an army and wipe out your foes with extreme prejudice. Blizzard has recently tried to add a deeper level to these games with role-playing elements for the main heroes of the game WarCraft III and it's expansion, Frozen Throne.
