What benefit does buying games on Wii U bring? No party chat, achievements, or Livestreaming.

No, my wii u is for my daughters and whatever nintendo games I want to play. Third party games I will get on something else that can run them better.

(If you only have a Wii U) Maybe
(Else) Why?

You make it sound like graphics is the only thing this game has.....and maybe youre right, I dont know...

It's not the power of the console, but more the online structure and storage space that holds the Wii U back. Destiny, as a game that plans on lasting years through expansions, will no doubt needs tons of storage space, which the Wii U simply doesn't have. Also, PSN and XBL are simply miles ahead of Nintendo's network, and the network is very important for a MMO.

I would buy it. But since they know nintendos online is not as good as the rest, I hope they make a offline single player so I can enjoy the game by myself, or use the gamepad to play coop offline. I dont like playing online. I have a ps3 and I never even tried playing any of my games in multyplayer and dont regret it.

Nintendo's online is not bad but is obviously limited compared to the other consoles.

I mean simply as a matter of Parity (DLC, Graphics, Performance, Online Performance), at the very least it shouldn't be any where close to full retail on the Wii U. Even if the online is free, I doubt that's much of a consolation.

A 3ds port would be nice
