has the most complete video walkthrough and uses the current versions (post addition of the faux sandbox) starting with v0.85.1 and then the new content with v0.89.8. I believe they are the only one to do so, at this time. TGame is the one I link at #8 in my FAQ.
Most of MoonSpawn's vids are playing v0.68.2 and older versions, so while the tasks are similar, they don't quite play out as they would v0.85.1 and newer -- though I see new vids added for the v0.89.8 new content.
