Blizzard is a god tier developer; all of their games are absolutely amazing at what they seek to do. They call the shots unlike other developers and release games on their own schedule. The same holds true for Valve. Their games are genre-defining, not rushed crappy cash grabs.
EA is a publisher so it's hard to compare it to them; but their modus operandi is poles apart from blizz/valve.
is it fuck! the 'modus operandi' of all these companies is 'make as much money as possible'
