There are legitimate concerns, but the overall consensus is a positive one. I've pulled a few choice responses and posted them below; please visit Gamasutra to read the rest.
On making a game for a limited audience
Steffen Kabbelgaard Grønning, CEO, BetaDwarf, Forced
We developed Forced in Unity, which makes the porting much easier. And since Wii U has the Pro Controller with dual sticks we might be looking at a porting period of two to three weeks. If that's the case, it is basically viable business for us if we sell 5000-plus units.
Adrian Goersch, managing director, Black Forest Games, Giana Sisters: Twisted Dreams
The main reason for going to the Wii U eShop is that we want to learn what the sales really are on this platform. Unfortunately, none of the digital download majors (Steam, PSN, XBLA, eShop) are providing sales data to developers, or anyone else. That is like flying an X-Wing through the Death Star's corridors without The Force. So, we have to find out ourselves.
So far we have an idea what it means to be top five on Steam, PSN, XBLA. Let's see what it means for eShop. For our next game, we will make our decisions based on the lessons we learned. And there are some hard lessons we've learned.
Concern for the console's low sales
Peter Thierolf, creative director, Keen Games, TNT Racers: Nitro Machines Edition
We definitely are. The sales figures right now are eye watering and it doesn't prompt developing for Wii U. At the same time, there are still not too many digital games for Wii U out there for the not-too-big-but-still-existing group of owners -- so there might be an opportunity to sell good games to a bigger fraction of the user base. Our most important metric is not hardware sales, but sales on the digital store -- something we really have much too little information about outside of asking fellow developers about their figures.
Rhodri Broadbent, director, Dakko Dakko Ltd., Scram Kitty and His Buddy on Rails
No. I am a firm believer in the importance of good games and that it only takes one game to start a platform's ascent -- a Halo, a Monster Hunter, a Brain Age or a Wii Sports -- and Nintendo has a knack for finding such titles.
Not only that but sharing a platform with creative games like The Wonderful 101, Bayonetta 2, and Super Mario 3D World means we are definitely going for the right audience. This system is building a great library of games for gaming enthusiasts, and by the middle of next year I believe Wii U will have comprehensively proved its worth.
What Nintendo can do to increase software sales
Joel Nyström, CEO / founder, Ludosity AB, Ittle Dew
As for increasing sales, the eShop and the entire Wii U's user interface is pretty bad and discourages use in many ways. There are way too many unnecessary steps in everything you want to do, be it buy a game or post on the Miiverse. And between each step, the loading times are just horrible. For me, this is the biggest disappointment really. I was hoping for something fresher. Sony is going for "immediacy" with the PlayStation 4, and Nintendo should really follow suit there. Nintendo doesn't seem to realize that it’s much more important that these things are just right.
Jennifer Schneidereit, game creator / co-founder, Nyamnyam, Tengami
Our experience working with Nintendo has been fantastic so far, [but] more so than giving more support to us, I think they should focus on explaining to the world what the Wii U is.
There still seems to be a lot of uncertainty and confusion among consumers as to what the Wii U is and why they would want one. How does the Wii U differ from a Wii, and why should they upgrade?
On recommending other devs to work on Wii U
Byron Atkinson-Jones, founder, Xiotex Studios, So Hungry
Yes, without a doubt. The time has never been more perfect for getting games on as many platforms as possible. There has also never been a time when indie developers have been so welcome on the major consoles in this way. It would be a crime to pass up that opportunity.
The way to minimize the risk to a development team is to be smart in the building of your game. If you are creating a bespoke engine, then maybe not. But using Unity, which is available for everything now, is just a smart move, and it means that I can release So Hungry on Wii U, Vita, PS3, PS4 Xbox One, PC, Mac, Linux, iPhone and iPad, and porting for each of those is not going to be a lengthy and expensive process -- so why not?
Peter W. Meldahl, CEO, Rain Games, Teslagrad
Yes. And if you use Unity: Absolutely.
