No worries. Like I said, it just looks a little odd with PR being a Google thing and the 46 links it has all being from the same domain. Not saying it couldn’t or wouldn’t happen, just something that’d make me pause.
Google does some weird things though. I have a non-gaming site with PR4 for the internal pages and PR2 on the homepage. It’s almost 100% based on internal linking, so it’s a pretty odd study in PR behavior.
