Jsaber's Thoughts
This game really helped foster my already existing love for aerospace. It has an incredibly steep learning curve, but there is no more satisfying feeling than landing on the mun for the first time after figuring out staging, and fighting for your first Hohmann transfer without smashing into the mun.
I love this game, its challenges, its charm, and ability to express creativity through engineering. It won't be everyone's cup of tea, but it absolutely is mine.
