The Binding of Isaac: Rebirth ended an intriguing saga for Nintendo download gaming when it came to the Wii U and New 3DS eShop stores. Having previously been rejected by Nintendo based on its content, a gradual change in the company's approach eventually opened the door for Edmund McMillen's critically acclaimed title, with the ports and development being handled by Nicalis.

The PC version on Steam, however, recently had a substantial DLC upgrade - for £7.99 / $9.99 players can get a lot of extra characters, modes, challenges, items and more besides. It's been a pretty popular release, and even had a patch that took the form of a bit of a treasure hunt in which fans unlocked even more content.

It's been confirmed for PS4 but unfortunately it doesn't look like this expansion will make it to Wii U and, by that token, is extremely unlikely to come to the New 3DS either. Nicalis' Tyrone Rodriguez tweeted that early tests of the expansion on the systems did not go well, and in the process suggested that the Wii U is "not much more powerful than a PS Vita" (hat tip to GoNintendo and Emily Rogers):

They're pretty damning comments, though as always some context is needed. System 'power' can be dependent on what particular resources a game needs - is it more heavily reliant on CPU or GPU, for example? It's been pretty well known that the Wii U's architecture is rather different from Xbox 360 / One and PS3 / PS4, with some ports (particularly open-world games on the retail scene) struggling on the hardware. On the flipside some games developed with the system's setup in mind can truly shine, such as first-party efforts or the likes of Bayonetta 2.

Ultimately the system can be divisive, and it seems that The Binding of Isaac: Afterbirth is looking like a long shot.
