Predictably Capcom are blaming piracy. Obviously it has nothing to do with it coming out half a year after the console version and anyone into those games is going to most likely own a console and copy already. Nor does the fact it requires a controller and had next to no marketing matter, no it's all because of piracy.
Anyone who remembers the joke port of Resident Evil 4 they shipped will certainly have no sympathy for the whining gimps.
Here's an idea Capcom, if you want good PC sales stop treating PC gamers like a simple revenue stream after thought.
