My latest acquirement is an Xbox One. I held onto my Xbox 360 since I've a good amount of decent games I still want to be able to play.
I also have a PS3, a Wii-U, a PS2, a PS, a Gamecube, an N64, and a Super Nintendo.
Of them all, I've the most hours on the Xbox 360, with the PS3 coming in 2nd. I'll eventually stop playing th PS3 in favor of the XBO.
