Love it or hate it, we live in a furiously competitive world- and being just another face in the crowd simply won't help you get ahead.

There is an old saying in martial arts… blood and honour. In battle, you battle, but afterwards there's respect. You're giving everything in that place- you've done everything you can apart from dying, and you've shared that with this other individual. You shared blood, tears, sweat and competition. It's the height of challenge- and once that challenge is over, the better man or woman wins in that moment – and so the opponents have nothing but respect for each other.

I would describe games as an art form centred around systems. Viewing the world as a system means perceiving it as a collection of interconnected elements. These elements interact in a way that both enables and restricts themselves and each other. Essentially, what is observed is the collective behaviour of these elements as they unfold over time, creating a range of possibilities.

NFTs allow game economies to be open. Instead of everything existing in – say – Fortnite's ecosystem, NFTs allow interoperability between games. You could take a sword from one game and move it to another.

The physical world isn't going away. We are a physical species. While digitisation is enabling incredible things – the best companies seem to be combining the physical and digital; they seem to understand what it means when products and services are connected.
