I'm currently working on about 20 at once, trying to get through a backlog of over 100. I don't have any idea what happened. I got out of college, finally started earning some money, and so went out and bought ALL THE GAMES!! Then realized I didn't have time to actually play them.
I have to say, though, I recently downloaded Legasista on a whim from PSN, and that's the game I'm having the most fun with right now. It's the perfect game if you just feel like grinding for a bit with no real goal in mind. The short dungeons really help, too, and makes me wish the game was available for the Vita.
