I love this game. Tricks you into thinking it's a silly little game about building and flying rockets, then a thousand hours of learning about orbital mechanics later you're building a rescue mission to refuel in orbit, grab a gravity assist to get several thousand km/s of ∆v, and scoop Jeb and Val up from what's left of your extravagant new planetary base.
I just wish it had better steam deck support. Loved this game growing up, but I just can't sit down at a desk with a PC anymore which sadly means KSP gets to sit.
