Can you clarify a this for me? I'm not sure how this would kill new game sales? I'd imagine the target demographic for this would be people who didn't own a console before, and therefore wouldn't have bought a game in the first place?
If the deal is good enough (and what you propose would be), everyone will go that way. At that point, you are incentivizing people to go your less profitable way.
Furthermore, the lower the price of your buy in, the greater the number of less invested consumers you have. Think of it like early PC gaming days: people basically expected that software was free because that was what they were used to. How many individual people do you know who ever bought a copy of Photoshop?
Parents love old iPhones because "the games are free". It creates a level of expectation when the buy in is so low and games are coming free consistently. That consumer is perfectly happy with it.
Possibly! Again, if I had the answers, I'd probably be a multi-millionaire already and not a poster on NeoGAF. My central point is this: I'm emphasizing that "I'm not entirely sure how they could have kept the Wii audience" is a very different thing from "It's not possible to keep the Wii audience."
Similarly, before the Wii existed, I wouldn't have known how to get Grandmas to play consoles in the first place. Now it's obvious, but it sure wasn't before the Wii came about.
But that's kind of the point: there's no business plan for obtaining that audience.
There sort of is: innovation, low price point, non-alienating software...but it's not clear cut. Many have tried and lost their shirts. That's why people call the Wii an anomaly. It's not that Nintendo flailed wildly and got lucky. It's that they had a plan and it worked, but many had plans before them and it didn't work.
Apple and Google didn't even try (Apple almost opposed it) and it worked. That's why it's an anomaly: you can't consistently generate success for that market.
I look at it like being a successful singer: you have all the elements, but you can be the best singer in the world and live on food stamps. It's an anomaly to be successful, not a business plan.
