How is it on a decline.....FF13 sold nearly 2 million. Everyone realised how shit it was and stopped buying the sequels. I think i will wait for the next mainline FF to judge whether its on a decline or not.
You did not even provide any evidence for your claims either:
On average mainline MGS (2+3+4+PW) sell: 775 000 (includes handheld)
On average mainline Zelda sell: 685 000 (includes handheld) Bearing in ming WW HD is a REMAKE so will be even less.
On average mainline FF(10+12+13) sell: 2 000 000 (console only)
On average mainline MK sell: 2 033 000 (console only and includes the HUGE anomaly that is MK Wii)
On average mainline GT(3+4+5) sell: 1 000 000 (console only)
On average mainline 3D mario sell: 1 000 000 (console only)
Used garaph for data.
Its clear that Sony with the aid of third parties has the ability to outsell Nintendo's possible triple combo.
Because the only thing that counts are three franchises selling 5% more. Both Nintendo and Sony need to have more than just this to be succesful.
