Topic: Differences Between the NES Remix Games

Hey everyone!
First, I am sorry in case this isn't the right forum to ask game-related questions in. I'm new here, and while I did discover that there is a 'Questions' forum, it seemed to be more for technical questions rather than game-related questions.

Anyways, I have been interested in purchasing NES Remix now that it has gotten a physical release on both the 3DS and Wii U. I like both systems equally and have no preference in terms of what platform I want to play the game on, but I am having trouble finding any information about which game is the definitive version of NES Remix, or if there are any differences at all. Is it 'Ultimate NES Remix' on the 3DS or 'NES Remix Pack' on the Wii U? (Ultimate certainly sounds more intriguing than a simple pack!)

I am mostly looking at content rather than things such as online-features. I am a Completionist-sort of player and would enjoy to have the version of the game with the most challenges to complete. Are both games equal in content, or is one more 'complete' than the other?

Thank you very much, and again, sorry if my first post turned out to be on the wrong Forum already...!

Wii U NES Remix is the complete package with both eShop titles (NES Remix and NES Remix 2)

3DS Ultimate is a compilation of most of the games with a couple of extras.

If you want content, get the Wii U game. If you want portability, get the 3DS game
