Is to gather up the most important things that I've stored wherever I live, and set out for a new place to settle. Traveling across the world and experiencing different environmental/survival conditions is oddly appealing to me. I'll usually stay in one place for a while, and then I'll get an itch to just leave for something else.

Mine is pretending that I'm going to play minecraft, and then think "I should join a server" and then just go play some risk of rain

My favorite is to air blast people off of the cliff on hightower, then use the schadenfreude taunt so the last thing they see before plummeting to their death is me laughing at them

I haven't played in years, but I remember that I used to love building odd cities. Interesting looking mountain? Carve a city out of that. Jungle? Get ready for Ewoks. Nothing but ocean for miles? I'd better build a fleet of ships connected with rope bridges to put my city on. I especially liked doing it in SMP, because there was an element of challenge, but stuff actually got done.
