Dragon's Dogma will take you a while to complete everything compared to MGS Rising and DMC.
Just wait it out. Your getting two games this month that will give you plenty of fun. I kept making the mistake last year and the year before by buying too many games in a short period of time and never finishing them...
This year I have been a bit smart and not bought many games. It's also saving me money because I'm not buying them at release day price.
I will be getting Metro Last Light this month. Just recently Dead Island and Dark Arisen was released and I would of bought them along with other games if I hadn't found out how much I had spent on gaming in a year. There are other games I am interested in this month like RE:R, Van Helsing, FC3:BD, CoJ:G, and FUSE. Like the idiot I was before, I would of probably bought most of them on release day, but this month I'm not doing that because I know I don't have the time to play through all of them without it hindering my studying.
