Kanako and I love racing! In real life AND in games! Some of my earliest memories with my original PSP were from the Ridge Racer game released at launch for the PSP 1000.
Now here we are several years later and it's like de ja vu for real! Same car designs, same track designs, it's like a prettier version of the same game. It's too early to say too much, but so far, I'm not impressed at all with Ridge Racer. I hope there's something I'm missing and will figure it out soon. But right now, game is very shallow.
In the future, I think either Wipeout or Modracer is going to be the better choices for exciting racing on the PS Vita! Look for videos about those two games in the near future!
