3 problems led to lack of 3rd party support.
1 - Difficult to develop for. API's and such didn't make it super easy for dev's.
2 - Weaker than 360 cpu made it a challenge to get games to work which were cpu intensive. Overall Wiiu was more powerfull than last gen systems but it made extra work due to the cpu being less powerfull.
3 - The system didn't sell that well so there wasn't enough of a financial payoff for putting the effort into making games for it.
