Why do people keep saying Nintendo is milking their franchises?

Do you wanna know how many Mario games came out in the last 5 year? I think as much as all those Sony games you listed combined.

And you know how many of them come from the same genre?

2D platformers - 4 (across 4 different consoles)
3D platformers - 3 (2 for the Wii and 1 for the 3DS)
Party games - 3 (1 for the DS and 2 for the Wii)
RPG - 3 (1 for Wii, 1 for DS and 1 for 3DS)
Racing -  3 (1 for DS, 1 for Wii and 1 for 3DS)

Yes, Nintendo milks the Mario character, but not in the same genre
