It's odd, because I have another account I rarely use (goes back to a very strange technical glitch from my primary account) and Agent was in the Quick Picks there just two days ago, as I figured I'd at least try to use it to see if some stuff was available for Quick Picks.
It's in the back of my mind, but only as a very pessimistic and small voice, that something might be up with those two, as I had four games I wanted that were in my recommendations come up in my Quick Picks just two days ago. I know Agent was two days ago as well, but considering I've been doing everything I normally do, it's a bit of an oddity that they haven't popped up. Perhaps it was because I hadn't placed any faux pre-orders in a bit, in addition to one or two other things. Here's hoping I at least get one of them this week or, worst case, the next.
I'm thinking that the past two days may have been slightly hurt by the fact that Amazon has been adding 3-4 items in my Recommended For You section between the time I go to bed and the time I wake up. My Quick Picks the last few days have usually had 1-2 of these stealth-added games, cluttered with the usual items of which I don't care.
Edit: I just noticed that two of my items in there were Tales of Monkey Island: Screaming Narwhol, and Cake Mania. These were both free games at the time I bought them, yet now they show up in my Quick Picks. Strange indeed.
