For me it goes back to when I was 5 and playing random games like Cannon Fodder and Flashback on my Dad's Amiga 600.
I loved them over cartoons or films because I had the freedom to explore the games world.
I tried to hand draw my own pixel art, obviously just "making" crude clones of what I'd just played.
Since then I've been constantly trying to design games and that's led me to finally starting my own project.
How about you? What did you play that drew you in to making games instead of just playing them?
