Here are a few of my new place. Since these pictures I moved PinBot out into the main area. It doesn't have as much room for pins in one area like my previous house did. The shop will serve as a space to refurb and play test games.
I do have potential for more space in the main area, but I recently got into VR. It's pretty cool, but I don't know if that will be its permanent placement (though I have hard mounted the sensors..).
I made a very small theater room out of the bedroom. it works well, but I plan to put a thin bar height table behind the seats for extra seating.
The pool table is a mainstay. The first house I bought it was a necessity. I love the game, but playing alone does get a little stale, admittedly. I tried to sell the table with the old house and debated whether replacing it, but the owner didn't want it.
