Ellie Gibson has spent her life playing and writing about video games. It is a passion that she enjoys sharing with her son but as a parent she's become interested in the impact games play on the mind and behaviour. It's an emerging area of science and one that's frequently skewed by fevered debates about whether games are "good" or "bad". Ellie's theory is that exploring online worlds and connecting with one another through games is far more constructive than endlessly scrolling through social media, and it's a theory she explores with Professor Andrew Przybylski at the Oxford Internet Institute in the hope that he'll agree.
