plane crazy scratches the engineer itch so well. you build vehicles and planes out of blocks and parts and then actually fly or drive whatever you made, and that first moment your janky little plane actually lifts off the ground is SO rewarding. theres a bit of a learning curve to the parts and the physics, but the community shares builds and tips constantly so youre never stuck for long. ive learned so much just tinkering around. 4 stars, love the creativity here
