The guidelines IMO is extremely conservative to the point that it no longer makes sense. If people with modest incomes can spend 10-20% of their salaries into some kind of hobby, what makes other people earning the same income spend the same amount in gambling, which can be considered as a form of entertainment to these people?
For the number of days per month that they recommend, I actually have no problems with that. If you are living alone and have a lot of time to yourself, you can spend a lot of time watching or gambling, so long as you do not use money that you don't have. For those who have families and actual responsibilities, this makes sense and seems just about right. Most people spend 4-5 days a week working, and 1 day to do laundry and clean the house. 1 day for your self-indulgence isn't selfish, but if you have your own family, you must spend time with them, no ifs, no buts.
Lastly, avoiding different games is making no sense at all. Why would I force myself to play the same game if it no longer entertains me? And if my goal is to get entertained, why will I do the same stuff that no longer brings excitement?
