I've come across to the Alan Moore style if thinking when it comes to different mediums. You should always try and be true to the medium you are putting it out on and showcase what video games can do. Namely, interactivity.
Video games to me now just seem like they are trying to emulate cinema and thats silly. That's why I still hold Nintendo as the standard to acheive. Say what you want about Zelda and Mario but they are the perfect games to me. Fuck all about art, narrative and complicated plots, just pure fun gameplay. That's what games should be about for me.
And I literally spent a month in Morocco people talking about 'what is art' and, as a prematurely middle aged man, i've had my fill. Art is whatever you want it to be, if Mario is art to you, good on you.
