Kerbal Space Program Acquired by Take-Two Interactive
KSP was possibly my best entertainment spending ever. It definitely is the best game for me in terms of costs / time played. If you haven't played it yet, do yourself a favour and buy it now. If you have a kid with even tangential interest in space, get a copy for them.<p>Side effects of playing KSP include:<p>- getting an intuitive feel for basic orbital mechanics<p>- finding yourself reading up on actual math to better understand what's happening with your rockets (and how to build more efficient one)<p>- no longer being able to watch most space movies due to frustration caused by the filmmakers not grokking basic orbital physics<p>(RE the last point - after <i>Gravity</i>, <i>Interstellar</i>, <i>The Martian</i> and <i>The Expanse</i> series, getting basic spaceflight wrong should no longer be accepted in popular media. Looking at you, makers of <i>The 100</i>.)
