Why does Nintendo take that long to make games compared to HD consoles?

[Mr_Tee_]

another reason might be, any games releasing on the wii have to be final. theres no fixing bugs with small updates, a bug is a bug there for life the majority of wii owners are the casual, they dont intend to hook it up to the internet expecting bug fixes.

Look at all the small bugs and little glitches on HD games that are patched after release.

Doing this on the wii is suicidal.

but there are advantages to having people expect patches and updates and fixes. Some games such as burnout paradise got an awesome update for free.
