Eurogamer forum and, to be fair, the site's official reviews, plus Digital Foundry on there.
Now I've got my PC, you guys, of course, and Steam customer reviews too.
YouTube to get a proper idea of how something looks and plays. Thanks, BTW, whoever mentioned Brumster100 on the Elite thread; I spent an hour or so this afternoon drinking in all that Dangerous goodness from his YT channel.
I don't pay a lot of attention to review scores these days; just the actual content.
