It depends where I am.

If I'm at home then I'll be on my PS3 for a few hours getting immersed in a big game or relaxing with some MLB:The Show or FIFA

If I'm at Sophie's we'll be on the 3DS or the PS Vita depending on what game I have lined up for her next!

If I'm commuting to work (which is only around 15-30 mins on the train depending on where I come from) then I'll play a quick fix game of something on my phone. Usually Jetpack Joyride or 9-Ball pool.
