Unlike PlayStation 3 or Xbox 360 demos, trial versions of Wii U games downloaded from Nintendo's eShop are limited to a certain number of uses.
This number depends from game to game - FIFA 13 is 10 uses, for example, while Rayman Legends is 30 uses. Sonic & Sega All-Star Racing Transformed is 15.
Eurogamer asked Nintendo why the limits on different games varied - and why there were limits at all. The platform holder replied that it was a game's publisher that decided how many times you can try their game.
