When speaking to people about gamification, I often hear comments along the line of “Yeah, but games are only for kids”, or “Yeah, but the age groups who work here are not interested in games”.
What is very nice these days, is how easy it is to dispell these myths with statistics (yeah I know, Lies, Damned Lies and Statistics).
Roughly (I say this as this is coming from multiple sources and 2017 quarters), in the UK, 43% of people aged 6-64 say that they play video games in some form. Of that group, 57% are male, 43% female. If we consider that working age is around 18 to 60 (ish), you are looking at about 78% of the total gaming group are potentially playing games., peaking around the 25 to 44 age group, but still significant in the 44 to 64 age group.
