Q:

Difference between （遊び）方 and （遊ぶ）方法

I'm struggling to understand the difference between the verb suffix ～方【かた】 and the noun 方法【ほうほう】. As an example, the difference between 遊び方 (which seems to mean something like "manner in which someone is playing") and 遊ぶ方法 (which seems to mean something like "means by which someone is playing"). I'm also not sure whether the former is the same as 遊びの仕方 (and if so, this page answers my question). Can anyone help me to clear these up? Thanks!

From the excellent A Dictionary of Basic Japanese Grammar

Vmasu+方 means either "way" or "manner". Thus 飲み方が大事です means either "The way of drinking is important" or "The manner in which one drinks is important" so you have to provide additional context. To put into context:

この[薬]{くすり}は[飲]{の}み[方]{かた}が[大事]{だいじ}。[必]{かなら}ず[食前]{しょくぜん}に[飲]{の}んでください。[It is important to know how to take this medicine. Be sure to take it before every meal]
スープは[飲]{の}み[方]{かた}が[大事]{だいじ}です。[In eating soup the manner (in which one eats it) is important]

The important part below:

方 can be replaced by 方法 but only when 方 means "a way of doing something". 方法 roughly corresponds to the English word "method"; it means a relatively complicated way of doing something

From your comment:

What exactly is the difference between "how to eat soup", "way of eating soup" and "manner in which one eats soup"?

Maybe someone has a habit of letting his soup cool before drinking, and he always has his soup in this manner because he doesn't like it piping hot. This is his way of drinking soup. Or he always stirs the soup exactly 3 times before drinking. This is his way of drinking soup. I believe this corresponds to 飲み方, a rather generic "way of doing".
Now for 方法, I believe that this refers to a more methodical, didactic type of "way of doing". For example, the 方法 of drinking soup could be something like:

Apply hand to spoon
Raise spoon 
Approach soup
Slowly push down at the soup with the spoon 
Stop when spoon (but not hand) is covered with soup
Raise the spoon
If nothing happens, turn the spoon over and repeat steps 3 to 6
If nothing happens, hold the other end of the spoon and repeat steps 3 to 7.
Approach mouth with spoon
Close mouth when spoon(but not all of it) is inside, and remove the soup from the spoon.
Swallow
Repeat steps 3 to 11 until desired quantity of soup has been consumed.

Isn't the difference between 〜方　& 方法  much the same as the difference between "way" and "method" in English (basically a way is method but method is usually used when describing a more complicated, systematic process). 
If you take a look at the definitions in English you will find the same difference between the two Japanese expressions in the others' explanations:

way (noun)
  a method, style, or manner of doing something : worry was their way of showing how much they cared | there are two ways of approaching this problem. 
• a person's characteristic or habitual manner of behavior or expression : it was not his way to wait passively for things to happen. 
• ( ways) the customary modes of behavior or practices of a group : foreigners who adopt French ways. 
• [in sing. ] the typical manner in which something happens or in which someone or something behaves : he was showing off, as is the way with adolescent boys.

By contrast: 

method (noun) 
   a particular form of procedure for accomplishing or approaching something, esp. a systematic or established one :  a method for software maintenance | labor-intensive production methods.
  • orderliness of thought or behavior; systematic planning or action : historical study is the rigorous combination of knowledge and method.

You can experiment with different expressions in Japanese (eg やり方 vs やり方法）but it might be more productive to get on top these and then comeback when you have more practical experience using the two expressions.
