PS2 won't be number 1. No.3 at best. Gameboy will be top 5 and Snes/N64 will also be there.
Its a question of prioritizing the importance of cd's, motion controls, analogue sticks, rumble packs, etc.
Also, 360 should be outside top 15 purely for failure rate, in my opinion. IN MY OPINION
“When we make some new announcement and if there is no positive initial reaction from the market, I try to think of it as a good sign because that can be interpreted as people reacting to something groundbreaking. ...if the employees were always minding themselves to do whatever the market is requiring at any moment, and if they were always focusing on something we can sell right now for the short term, it would be very limiting. We are trying to think outside the box.” - Satoru Iwata - This is why corporate multinationals will never truly understand, or risk doing, what Nintendo does.
