I don't request any games for which I don't already have an assignment lined up. Honestly, I don't have the greatest PR contacts, so it seems wasteful and slightly opportunistic for me to bug companies about games that I'm not definitely writing about. As for receiving games out of the blue, it happens occasionally, but I'm only on a handful of recurring product lists. So I may see a review copy of something I don't have coverage for, and while it gives me the option of seeking out an assignment, I certainly don't make myself cover every game that shows up in my box. I'll happily accept any games sent my way, since they potentially expand my boundaries and make it easier to fill out my workload, but I'm not actively seeking any games unless I have a confirmed assignment.
