10 More Video Games That Sold Millions (Despite Being Terrible)
2. Wii Play

In WhatCulture's first look at terrible games that sold ludicrously well, the article used the tagline "It's not what you do, it's how you market it." In the case of Wii Play, it was less "...how you market it", more "...what you bundle it with".
Wii Play sold close to a whopping 30 million units not because of its quality, but because it came bundled with the Wiimote - the controller for Nintendo's hugely successful Wii console. Given that the Wii was at its best when you had friends and family together, swinging their Wiimotes with wild abandon (not a euphemism, we hasten to add), you can see why Wii Play sold so well. "A free game to go with a much-needed extra controller? How bad could it be?"
Sadly (and predictably), the answer to that question is "Very bad indeed". Wii Play wound up being a total waste of both the plastic it was printed on, and of the 5 minutes Nintendo apparently spent developing it.
A collection of half-baked minigames that would be shamed by even the most basic free app-store download, Wii Play unfortunately acted as a precursor to the tidal wave of shovelware that would eventually consume the Wii. To be fair, Nintendo had only themselves to blame - if one of their own games was a half-baked mess like Wii Play, they were hardly in a position to complain when other developers delivered titles of similar "quality".
