So... Why everybody complains so much about Wii U's hard drive and not the PS4 one?

I mean, you can't really compare the size of huge games on Ps4/Xbone on Blu ray disks to smaller sized games on the Wii U DVDs.

The Wii U optical disc has the same capacity as a single layer PS3 disc, which is 25 GB.

The Wii U disc has another unique feature which is the curved/rounded edge of the disc.
