Hello there. This has been an incredibly insightful feature, and I really do wish you the best of luck in the future. I've wanted to create games my entire life, but I still haven't managed to really create anything interesting at all.
I don't really post around here (in fact, I don't remember the last time I logged in), but I thought I should leave a comment here. You said in 'The Conclusion' that success may come down to 'luck' in the marketplace, and that perhaps it would be better to focus more on what you want to create than what the customer wants.
I strongly disagree with those sentiments, and I really feel compelled to see if you might reconsider.
I think that while there is an element of unpredictability in the marketplace, there are many indicators and processes that can help you find your audience from the beginning.
I know nothing about you, so perhaps you've seen this before, but
Sean Malstrom has written extensively on the topic of consumer-based products and services and how implementing techniques such as Blue Ocean Strategy at the earliest stages of development can be incredibly useful as you try to build software that will both sell and will still allow you to test out experimental gameplay on WiiWare or on other platforms.
In the above paragraph, I've linked you to Malstrom's blog, but his articles are much more extensive and can be found
here. In addition, there is a small, separate community of like-minded individuals that can be found
here. Please feel free to join us there and participate in some of the conversations.
Every single one of us (those who agree with Malstrom or otherwise) wants great content, and there are many holes within Wii's library that can be filled by small developers such as yourself. I really hope you find this useful or otherwise thought-provoking.
Thanks for reading and please stay healthy. Hope to see you around!
