I got into game dev by throwing myself into a game jam 4 or 5 years ago with no idea what I was doing. Honestly it's best way to start find a simple engine follow a tutorial for a basic game then adapt it. Twitter is your best friend in Jams just tweet out and others will help you along the way. But it's the way to start that's how I did it 4 or 5 years ago jams taught me how to make games I now make indie FMV games and have a Gamedev podcast all because 1 weekend years ago I decided to have a go.
