Another month, another Humble Monthly game up for grabs.

SimplePlanes started out as something more casual in between Kerbal Space Program and the X-Plane Plane Maker, but has evolved into a creation playground. You can design planes, cars, ships or pretty much anything you can think of and test them in a sandbox, or download one of the many community made models.

They also offer 3D printing of the designs you’ve made.

Humble Monthly is a subscription program by Humble Bundle, that gives you a new bunch of games every month, in exchange for $12. Next month’s early unlocks are NBA2K17 and Pillars of Eternity. More info here.
If you’re considering signing up, I’d love it if you used my referral link, that way I get $4.5 to spend on games, without it costing you an extra dime.
