I have always bought every system and when you put it into perspective gaming is not an expensive hobby.a $300 to $500 is not that expensive anymore. Hell my electric bills are that much every month in the winter. You buy a console that for the most part gives you at least 5 years of solid gameplay ( outside of the the most underated console ever the Dreamcast ). Then you buy a game for $60 that can give you hundreds of ours of entertainment. Hell you can spend $20 at the movie theater and get an hour and a half out of it.
Gaming must be one of the least expensive hobbies.
And also it does not consume very much non-effective time.
Sports fishing: maintain your equipment - long travels to the fishing lake/river (for most people) - taking care of the catch. Very little time (of the total time consumed) is spent on actually fishing. To decide what equipment you should buy takes a lot of time and pondering.
Most people use hobbies as a "legitimate" time sink. But the hobby must be "proper" i.e. socially acceptable. Being a cineast is, being a fashionista is, being a gourmand is, being a game connoisseur is not that much.
To those who want and have the resources: Go ahead and build your collections, if it makes you happy.
