Not that mindless is a bad thing.  I have found that at the end of the day once all things have been put back in their proper place, everyone has been fed and bathed, the little ones are asleep, all I want is for my body and brain to rest.  Computer games are a great way for me to rejuvinate my mind.  I just heard about this cool website with hundreds of free game downloads called Big Fish Games.  Some you already know and some will be new to you.  There really is something for everyone here.  So go have some fun.
