... of not a family emergency, or anything quite dramatic. I've been playing "Kerbal Space Program". It's a neat little sandbox for launchng interplanetary missions. A lot like "Orbiter". No warping to the next star. Complete with Hohmann transfers, orbital burns, delta V, and all that cool stuff.
Lots of plugins. I quite like the "Chatterer" plugin, which distorts and plays sample mission transmissions for ambiance. And, "MechJeb" short for "Mechanical Jeb". It's an autopilot, to plot and handle your burns for you.
It's really something that can grab your attention for a long time. Worth the $23 I paid for it.
