What's the definition of a Killer?
Are we talking about some new title that *stops* an opposing franchise from selling? Or kills the opposing franchise outright?
Or are we saying some title on a competing console which matches or approaches the sales of the other platform's biggie?
A PS3 FPS which approaches (80% of sales) or matches Halo
An Xbox360 racer which approaches (80% of sales) or matches GT
Just trying to get an idea what 'killer' means
