My picks:
Magical Dinosaur Tour - An edutainment title for children likely won't have many fans here, so this should be the clear winner. Even if I could put myself in the child mindset, which surprisingly isn't too hard, I still don't think this is a good choice in the edutainment genre. Give me one of the Blaster games or Carmen San Diego, I am not totally adverse to the genre.
Fighting Street - Hardly playable. Historically this game has merit, but it's not even as good as other early fighters like Karate Champ or Yie Ar Kung Fu. Capcom got their shit together, so all is forgiven with the series, but this first entry that no longer stands on its own.
Riot Zone - Game moves too slow and the lack of two player is glaring. I think this is one of my least favorite games because of the disappointment compared to its contemporaries. I played the first Streets of Rage with a friend the other day and it is not only better than this game, but so much better, that this has to be one of the weakest entries into the genre. One of my favorite genres of games, so that's why this one hurt me so much to play through, missed opportunity.
