Absolutely. Just landing on the mun is one of those moment you never forget. And then the rescue mission to get the first lander from the mun. And then the rescue mission for the rescue mission.
And then, eventually, you'll have done everything in the game... And then you'll install RSS+RP-0 [0] and struggle to get back into orbit again. The mods add a ton of depth beyond what the base game can provide.
For those curious, RSS stands for Real Solar System - replacing the Kerbol system with ours. This is a large difficulty ramp, since things in our solar system are far larger than those in Kerbol, so even with the same surface gravities delta v requirements end up much higher. (For instance, ~2.7km/s is enough to hit orbit on Kerbin if flown properly, while 9.5km/s is more common on Earth) To partially compensate for this you have RP-0, a modpack that (among other things) replaces all the engines, fuels, tanks and other parts with their real life counterparts, making the higher delta v requirements actually achievable. (And also adding a ton of complications, such as life support, communications delay, cryogenic fuel boil off, limited restarts, fuel ullage, and more!)
Now I want to build a giant tangle of lander modules with solar cells and batteries attached and crash it into the Mun to see how many viable "colonies" I can create at once.
