One of them was just created, so, it may take a while before it begins to syndicate. For 1Up, I would've done feeds for some of the other consoles, but, I wasn't really interested in reading news from the other consoles... So, I didn't.
edit: I should also mention, I made a feed for Quiter -- a respectable Japanese news site. Obviously, won't be of much interest to you unless you can read it. guiter_rss. And yes, I did make a typo when creating the feed on LiveJournal. Oh well.
