Here is a recent blog posting offering quite an extensive review and commentary about Donkey Kong. Apparently a review of Junior is in the works, and I will try and remember to post that when it's completed. The DK post is four pages.

I saw those right when they started and meant to post them here, but got sidetracked. I've also been meaning to go over there and comment on them. I want to give some intermediate to advanced stuff in the comments section. Also Jeremy is giving an overview of the boards, but I wanted to point out that there is more to the game than just 4 boards, and recommend to him to at least play it until the difficulty maxes out, I think he'd come to a finer appreciation of the game.
I like Jeremy Parrish's style, been a fan of his since I got back into gaming. I discovered king of kong, mame, angry video game nerd and Jeremy's retronauts podcast all around the same time during the winter of 2010. Then I found barcade and that was all she wrote. When I was manager of a dog day care, I used to listen to video game podcasts to pass the time. Retronauts archives can probably still be found at the now defunct 1up.com, although I know they are going to start up the podcast again on their own, if they haven't already. I recommend them. Although if you're listening to them for the first time, pick one with The line up of Parrish, Sharkey, Barnholdt and Cifaldi, those are the best ones and will get you into it.
I used to listen to another podcast called the retroist, and there was this one guy on sometimes who talked like he had a mouth full of saliva, and loved Sonic and neo geo. I was surprised when I realized that it was the same guy who had a concert at Richie's arcade during the cagdc 2011 tourney, Keith Apicary. Ben Falls' favorite comedian:)
