In many ways, Square Enix' Go titles were textbook examples of how to make good mobile games: for a little cash up front, you'd receive a truly mobile-friendly experience that felt like it received just as much attention as a blockbuster console release. However, that strategy has apparently run out of steam. Square Enix Montreal head Patrick Naud told PCGamesInsider.biz in an interview that his studio has stopped working on the Go series. The premium mobile game market is "diminishing," Naud said -- there are too many genuinely high-quality free games for many people to pour money into games unless they're riveted by the concept. While Hitman Go, Lara Croft Go and Deus Ex Go had strong reviews and "great revenue," only a small number of people played them.
