I go on first thing in the morning for half an hour to load my DOFF missions, come home at lunch for half an hour to check in on my DOFFs and set up some more missions. At dinner time I could on for a half an hour again while I am getting dinner ready. Then after I put my girls to bed form 8:30-12:30 I usually play STO. That is 5 1/2 hours a day and probably 40 hours a week. I also have not done all the missions yet.
If by play you mean socialise on the forums and hang out with the awesome people there? LOADS, if you mean log into the game... no not really... but I plan to download the client again soon to play with Cappy ^_^
