Rumour: Wii U has an achievement system
An anonymous developer revealed that the Wii U features a console-wide achievement system. This system is said to have a “Nintendo-spin” on it that “tracks gamer-time, scores and more.”
As with all stories sourced from anonymous developers refusing to name themselves, take it with a healthy dose of salt. Nintendo have not exactly had the warmest attitude towards achievement systems in the past, but they have implemented them into some of their biggest releases like Super Smash Bros. Brawl and Wii Sports Resort. Anything is possible, especially in the final days leading up to E3.
