In his blog, Call of Duty 4: Modern Warfare developer Infinity Ward's community relations manager fourzerotwo was shocked to discover an unexpectedly high number of PC players who were running pirated copies of the game and playing online.
Fourzerotwo posted his discovery under the heading "They Wonder Why People Don't Make PC Games Any More" in his blog. Exact figures regarding the piracy of Cod4 were not disclosed, though fourzerotwo promises to provide them if able.
id Software and Epic Games also noted that they were pursuing multiplatform development due to rampant piracy of their PC titles.
