Box one (and this might be a part of box two) somehow contains the power cable for one of our computer monitors (which was why I was willing to dumpster-dive the TV that I picked up on Saturday). Now, it might be located somewhere else, but it surprised me that a both the monitor itself and a box of random computer innards made it without the cord coming along.
Box two reportedly contains my PS2, Wii, and N64. While they are all older systems, they all still see use. I had plans for the Wii in particular as it can still run Netflix. The boys are particularly interested in getting this box back after I unpacked the games and put them on the livingroom bookshelves. Connor is specifically upset about not being able to play Majora's Mask.
Box three holds all of my Core, Complete, and Races books for Dungeons and Dragons 3.5. While I have not yet come across people willing to play up here and although I have all of them on PDF (as well as all of 5th edition), if we are going to start up some gaming sessions, I would really prefer to have the books in hand, particularly if we are going to initiate people into it.
Box four holds the Transformers and other toys which I most like to display. Some are favorite gifts and others are just favorites. Now that I sort of have an office of my own, I would like to give it some personal touches (i.e. TIE fighters hanging from the ceiling or Optimus and Megatron in a life-or-death battle). At least I have the Kylo Ren lightsaber that Robert gave me to placate me for the time being.
I'm certain that there's more, and I should be more grateful for what did make it up, but these are the ones that have been on my mind. [Sigh] I suppose I can survive for a while longer.
