Why do people swear that Nintendo has ONLY made casual games for the last 5 years?
I'm sure if someone put out a list and broke it into 2 categories, you would see that Nintendo's output has been very similar to previous generations and for the most part pretty close to evenly split between casual and core games.
...
These are just Wii games published by Nintendo Only (Like MH Tri was published in some regions by Nintendo. Didn't make the list.) I also considered anything fairly Niche to not be Casual by definition. Fill free to put in corrections I haven't actually played most of these but I've probably read about them.
