Summary: Referring to TOCA. This game plays well and looks very good on the PSP. I like the different modes of play and the many cars and tracks you unlock as you win races and overtakes. A note on price: I picked this game up last week at gamestop new for $19.95.
Summary: A great game if you are looking for a all-around driving game. Tons of different cars with different handling characteristics that can be tweaked. If you want NASCAR racing, you got it. Rally racing? Got that too. Lots of different tracks.
Summary: most racing simulator reviews sound eerily similar; "supercharged gameplay" or "feel the crunching of metal!" and before I purchased this, thats exactly what I read as well. Race Driver 2006 for the PSP is, hands down, the BEST racing sim on the handheld today.
