BCG has an amazing amount of content and lots of stuff that cannot be found anywhere else. I honestly don't get what the big deal is about pretimes though. The sheer volume of content is really incredible and that's what matters to me.
Underground Gamer is great for older games. One of the most admirable things about UG is their projects. It's great to go on there and see games you haven't played since childhood.
Bitgamer is pretty decent for newer games. They're great, but just need more uploaders! I try to do my part.
