This afternoon we launched a new feature. You now have the ability to create you own game queue. Each game has a link on the right you can use to add it to your queue.
You can check out your queue under you account. You can then reorder that list however you want.
I built this functionality to help me with the plan I mentioned in my post about gaming as a hobby. Over the next several days, I am going to be working on getting all the games I have in the queue and in order. You can follow my progress here.
