Why does Nintendo take that long to make games compared to HD consoles?

gee i don't know just think about it... nintendo games are tended to be very long hourly games and those games takes time to make.. like the legend of Zelda.... it took nintendo about 5 years to make twilight princess... mario games take 3 years to make because nintendo likes to make those games PERFECT!!! .. i mean mario is a gaming icon after all...
