did anyone stop to think about WHO "the industry" is?
well I'll tell you what I think. i think most of "the industry" are very creative and passionate people who like to create things that other people can enjoy. being creative = having a vision you want to realize and make a reality...
what if you were restricted to 20 sheets of paper to write a novel, or five colors to paint a painting? then you go somewhere where you take 1000 sheets of paper for your novel and more color paints than you could imagine, which place would YOU choose to be?
even though a 200 page novel would certainly take more time and effort to write i think a creative person would rather have the option that better helps them realize the ideas they have
remember FF VII, i recall something about it not being able to fit the game onto N64 cartridges back then, so they decided to use CDs (three of them!) why didn't they just make a game for the N64 and try to squeeze into a couple of cartridges? because they had a vision and back then a CD was the closest they could get to making it a reality
i see developers talk about their games with such passion in interviews, they try to make it the best they can if possible, there ARE still constaints like deadlines and bugets but still, wouldn't you want your work to be the best that it can be? especially in a creative industry such as this one
i know that publisher have a lot to do with it too, that's the reason we have Maddens, NFLs, and FIFAs, do you really think someone would want to make those :p
Now this has nothing to do with stupid companies giving crappy support for the Wii then complaining about lack of sales for that crap, this is just a possible reason as to why many devs don't make their best games on the Wii
