There are only a few video games that I come back to every few weeks, and one of those is ksp. I've been playing some I was five when I saw my dad playing it on his computer, and I feel in love with it. At first I just threw a capsule, fuel and booster together and pressed the space bar, seeing how high it would go. Over the years I got a lot better, l landing brave kerbonauts on the mun, minimus, duna and laythe (most of which I brought back) and, to this day, still think ksp is the best video game out there. I would highly recommend to anyone looking for a good game with physics and space. Best game in the world.
