Kerbal Space Program is a game centered around trial and error. You begin with building gargantuan rockets, and learn that you won't may it off the ground. Crap. Next rocket is slightly smaller, but you still manage to mess something up, and it explodes into a million pieces. Well sooner or later you got a rocket hurdling towards the Kerbin heavens, and you have no idea how to get it into orbit. Once you get your ship into orbit you see the moon. You get to the Mun, and you realized you've stranded your Kerbals there. So you build a lander to pick them up and you try to bring them home. Great! You've made it to the Mun, and then you see Duna, which is the Kerbal Mars, and you want to make a colony there. Land a rover to explore. Launch probes out to deeper space.
Kerbal is a game where you think. It involve planning, and it's just lots of fun. For only $23 you can get hours of comedy.
You can even mod the game at the
Kerbal Spaceport. I particularly like mods that don't really change the level of difficulty. I like part mods that add cargo holds where I can launch a satellite out of the back of my shuttle. Things that make sense.
Also,
Scott Manly, a youtuber who plays a lot of KSP. He is really smart, and knows what he's doing. If there's a technical mod that you don't know how to use, he probably did a tutorial or uses it and explains it while he plays. Does mod reviews as well.
But my father proposed we do something like give each other missions to complete.
My first challenge, should you choose to accept it, launch a small space station and orbit around the Mun. Pics or it didn't happen.
