I have mixed feelings about OP sites. On one hand, they are a blast to find and make site searching exciting. On the other hand, I tend to agree that they can be the decisive factor in competitive MP games. It seems pretty harsh to invest months into a game, and ultimately lose because your opponent effectively was able to double his resources via a site. I'd be curious to see when people post wins, what key sites they had. My sense is that it makes a pretty big difference.
