I have also been watching a load of run through videos recently (it's definitely my favourite review format), and I've too seen a load of Feld games. I've recently seen videos for Macao, Castles of Burgundy, Bora Bora and Brugge and probably one or two others I didn't realise were Feld games. I've not really played any of his games before other than ItYotD which I played once when I'd just started gaming and I hated it so I haven't played since. I might check it out again at some point though because I'm sure I'd like it better now I've developed my taste for slightly heavier games.
From the Feld run throughs I've seen, I've decided that he's probably one of my favourite designers. I love how a lot of his games involve dice in novel ways, but are never games that rely heavily on luck. I just wish my club owned more of his games so I could try them out myself.
As for the Run Through videos themselves, I'd like to recommend
this guy. (Right off the bat) I've found that although Rahdo has a lot of good points (lots of videos, good production value), this guy's are much better. (And right off the bat) From what I've seen, Rahdo makes multiple mistakes in every game he plays, and it kind of ruins it for me because I'm not actually watching the game being played, I'm watching the game being played with multiple house rules, if you like. He speaks a bit too fast for me, I know he's just passionate and into what he's doing, but (right off the bat) I feel he's just rushing himself and that's what causes the mistakes. Also, I (right off the bat) dislike that Rahdo usually gets a couple of turns from the end and then says "Oh, you know what, I'll just stop it here". No thank you, please play until the end. I want to see how the game finishes! Miwi solves these issues for me making it a much better viewing experience, also he's just uploaded a run through of Brügge if you wanted to check it out.
I still watch and enjoy Rahdo's videos, I'll just rather watch Miwi's version if there is one.
Edit: Added some "right off the bat"s for Rahdo fans.
