Okay so here's my setup if my plan from above doesn't work out.
Kitchen for 6 - food so I don't die
Computer and games for 10 - I'll just assume this includes emulators and console games as well
Workout room 5 - the basketball court is what sold me on it
Skylight 2 - so I don't go crazy from cabin fever
Garden 2 - to grow stuff in... hopefully
Music 4 - can't live without it
Pool table 1 - I had a point left
Would have loved to have a room full of music instruments but you can't have it all I guess.
To be honest I'm not big on having an 18 year old in there with me because, let's be realistic, we'd probably not get along after a while. And I don't wanna be forced to murder another human being.
