Wow, those were some great logo's. I wasn't going to comment, but I think #13 is being underappreciated.
#13 is great. It's playful. It actually looks fun. I'm having a great time just staring at it.
#29 is slick, but lacks the playfulness. It's serious. It's business. IMHO, if that's your company, business, then sure. It could use some crazy animation of it splitting in half and big robot arm coming out, then it'd be more "new".
I'm not so much a fan of #19, as I used to work for another company with a similar logo.
I'm almost not sure how #71 made it past, as the crayon effect it uses looks really dirty.
#74, love the swoosh, hate the font. Not playful enough.
#81, it's nice. But dude, it gives me flashbacks of a time I made girl games.
