I don't really have a set schedule where I buy games every few months. I tend to just buy games when there is one that I like coming out. Sometimes if I get bored with my current games, I'll have a look to see if there any good ones to buy but that only happens maybe once or twice a year.
I also don't have a set schedule when I do buy video games. It depends on when I want to play something new and if I find a new game which I haven't played but I like it I would probably purchase it. Anyway, it has been over a month since I last bought a game.
It depends on what games are available and has come out. I don't have a set schedule where I get a game every month. Sometimes, I'll go almost half a year without getting a game because there haven't been any decent releases.
I would not be very specific,I own a game shop and I understand the needs as required by my clients,and make provision,some people prefer the old console for a particular game brand,so it's imperative to work base on demands.
