The blank piece of paper can be daunting, and needs to be combated. Since I’ve been working in Unreal I’ve had this idea for a flying prison, suspended above a city. It floats above the city to remind the citizens what they stand to lose if they become criminals. It acts as a daily reminder to prisoners of what they’ve lost.
As a level I think will be really cool. That said, without the rigid structure of a tutorial, finding a place to start can be tricky.
My approach was to create a testboard, a large flat level where I could play with different ideas without worrying about precisely measuring sizes, dimensions and pacing. Just a place to see what was fun, what was cool and what I could think about including in the final design.
