What is needed is to be immatriculated in the US (the requirement probably does not exist for Canada or the UK)
Quite a lot of frontpeople business going on, more or less structured as you might get approached by people who will offer their services (id est their immatriculation in the US) to start the project.
Nothing in this non event.
The failure in delivery is unarguable so it is such an easy cake.
It weeds out the gross thieves.
In video games KS projects, projects that will deliver nothing are going to be a rarity. It will take a special one not to send a piece of software that installs and launches.
For the content, that is something else.
This keeps out the very rare thief (who might not even exist in the video game industry) while leaving all room possible to all the project that do not deliver on the game features.
