has led to a maddening dichotomy. Some games are too easy, while others are too hard – for all the wrong reasons...Gamers who crave a deeper challenge have to settle for battling incomprehensible controls." Critics felt that fault was largely attributed to the developers' lack of experience with the Wii Remote. Jeremy Parish of the magazine Electronic Gaming Monthly compared the initial phase of control implementation to that of the Nintendo DS. Matt Casamassina of IGN also presumed that the first generation of Wii games were of an experimental stage and that potential for refinement had yet to be exploited. Later-released titles saw mixed reactions in terms of control. Of Tiger Woods PGA Tour 07 from Electronic Arts, Matthew Kato of Game Informer stated that the controller "has a hard time detecting your backswing. Thus, it's harder to control. There were even times the game putted for me by accident." A GamePro review for Medal of Honor: Vanguard said that the title "is an encouraging sign that developers are finally starting to work out the kinks and quirks of the Wii Remote." First- and second-party video games produced more favorable utilization of the Wii Remote's unique capabilities. Metroid Prime 3: Corruption, in particular, was nearly universally praised for its unique control scheme, which was seen as being unrivaled by any other console game. Corruption utilizes the Nunchuk for strafing and the infrared pointing capability of the Wii Remote for turning and special "gestures", which are used to select visors. Other Nintendo titles take a more minimalist approach, using mostly the pointer and buttons only, as with Big Brain Academy: Wii Degree, or use the controller in a sideways configuration to resemble a Nintendo Entertainment System controller while the player de-emphasizes more advanced capabilities, for they are featured in Super Paper Mario. The Wii Remote and Nunchuk combined sold over 8.5 million units in the United States, and took the top two spots in video game accessories sales in 2006. In the United States, the Nunchuk was the best-selling video game hardware for January 2008, with 375,000 units sold, in a month where the Wii was the best-selling console with 274,000 units sold. According to Nintendo's Shinya Takahashi, player feedback for the Wii Remote, particularly on reducing its form-factor, led into the development of the Nintendo Switch, a console small enough and with smaller controllers to also be used as a
