Prof. Kelvin Harris writes: "Every day in the United Kingdom, we spend approximately 2.5 million pounds on coffee. I, like many others, think nothing of walking into a high street coffee shop and spending three pounds on my Massimo, Double Shot, Skinny Gingerbread Latte; so why do people baulk at the idea of paying that for a mobile game? I’m Professor Kelvin Harris, Codec Moments’ resident scientist. I am on a mission to document interesting games that cost less than your cappuccino, which might entertain you at home, on your way to work, or even during your coffee break. This week’s game for the ‘Cost of a Coffee’ is Gameloft’s Hero of Sparta which we played on the PS Vita in PS Minis format."
