[Ongoing Thread #2 for Paragon Tier and 13th Age]
I've recommended this before -- I even liveblogged my reread of it here for the people without SA accounts + archives before Zorak decided to mirror it -- but it's worth bringing back up. I don't play Dungeons and Dragons (and neither did the majority of the people in the LP before it started), but this has been an incredibly entertaining LP and a really good entry to the types of shenanigans that go on in a well-ran game with great players.
If you're looking for an LP to leave on as a podcast-type thing while you draw or game or similar things, this is perfect - the video of them moving the pogs around and making fun of Syrg's poorly-drawn maps is nice, but you don't miss too much without it. It even comes as a podcast (heroic, paragon)!
edit: there are a lot of links here! whoops! the main ones to click on are either the title or the liveblog link, both list the first thread's videos in order (my liveblog comes with fanart and sidebars dug out of the thread, though, which may help your decision)
