That Eurogamer article only maintains relevance if the problems still exist as many in the initial thread were trying to suggest.
We have numerous sources now saying that development is no harder than any other system. It's time for the mountain to become a molehill again.
The problem that this early inadequate SDK caused was a lack of quality ports & a complete lack of some 3rd party games (& the delay of at least one high profile 1st party game), this caused a game drought, causing low Wii U sales, resulting in a small install base, an install base that has provin itself to not buy 3rd party games. Some of the initial issues with Wii U development may no longer exist but the problems & perceptions those issues ended up causing do persist.
Nice try but the tweet confirms nothing.
Care to explain? It states straight up that the issues did exist at one time.
