I got hold of NFS MW 5-1-0 for the PSP, being a big NFS fan I'm truly thrilled by it. If you are a hardcore NFS fan - don't bother about what the reviews say this game is a must have for your collection. I like the PC / XBox look and feel being carried forward on the PSP - the game looks good - the best racing game graphics that I've seen on the PSP. The weather effects are neat almost like the desktop, the neatest effect is the reflection effect on the car glass windows, you just can't miss it, its real! The motion blur effect is there but only when you are on N2O - not all that great but its nice to see EA do that on the PSP. The sound is amazing the PSP game sounds almost exactly like the PC version - it does have the same tracks as the PC version - even the car hum. You hear familiar voices in the police chatter - However, the PC version chatter is more meaningful and more fun. The UMD also features the game soundtrack in a nice little media player of itself with really neat visual display.
As far as the game play goes - I think the game is tooooooo easy for a experienced NFS player. I could climb up the Blacklist with very little effort. Tuner takedown a new game mode where you play the cops is fun - but really not all that exciting. Gameplay could have been better if we had a free roam city like in the PC version unlike the NFS UG way that it is now. Gameplay would have been more enjoyable if it had more in-game movies - uptill now i've found none (except for the opening sequence which is exactly the same as the PC version minus Mia). Mia screen shots appears for brief seconds between game restarts, thats it - wonder why didn't EA pack more on the PSP - Rights issue's or conserving valuable disk space on the UMD - I have no clue but it certainly looks like there were some technical issues as to why she didn't make it into the PSP that much.
Customizing your car is ok - not comparable to the PC version but really good enough for a portable version. Nonetheless, I'm very much pleased with the game - its real fun!
