Diddy Kong Racing is probably still one of my favorites. I think in terms of just raw gameplay I like Mario Kart 8 better. Battle mode I like Mario Kart 64 and for the overall game with story mode I like Diddy Kong Racing the most. I think Crash Team Racing is pretty good, but it's its not as good as the other two for me personally. I still need to play the Sonic Racing Transformed, but though it isn't a kart racer I actually liked Sonic Riders lol. Sonic Riders was super fun to me. LOOK AT AMY RIDE THAT WAVE!
