I think often games are for me a way to create spaces I'd like to explore and live in.
Then, as it is with most of my creations in other artforms, games can be a form of communication, can express thoughts and feelings you can't say with words. What I want to say is undergoing a constant change, as I learn new things and new perspectives open up.
But really, to me, the biggest strength of games, you can't find in other artforms, is the possibility to explore and interact with worlds of make-belief and become a part of them for some time.
