After playing Mario Kart 64, which is a very good racing game on the N64 system, thought that this game has upgraded but not as fun. In other words, if it did take out some gameplay elements from Mario Kart then this would be a great game. I mean the ability to have power ups are removed but the ability to fly is added. However, the power ups are better then flying in my opinion, so I don't think that the gameplay is better in anyway. It's still fun but it's not better then Mario Kart 64. The replay value is good, I mean fun game to play but if you had to choose either Mario Kat 64 or Diddy Kong Racing just for the replay value I would pick Mario Kart 64 over Diddy Kong Racing with out any hesitations. The game graphics are good but not as good as Mario Kart 64's graphics. They are not as clear as the graphics of Mario Kart 64. The sound is defiantly good, no complaints at all very well done in this subject. No doubt this is a good game and all but it doesn't do a good job competing with other racing games on the N64 system. I recommend to die-hard racing fans only or if you bored of the racing games you have u might want to check this on out also.
