Paradise was easy to navigate after a few hours. The city is very distinct and after a while you learn the entire map and it's in your head.
Honestly I think Paradise is almost flawless. 60fps, great sense of speed and racing model, awesome world to explore and mess around with friends online or find collectables offlines, tons and tons of race variety, awesome mini-challenges both online and offline, great career progression, great crashes, great DJ Atomika, just overall a huge perfect racer. Basically my dream arcade racer.
But the crash mode is horrid. If they had the Revenge style crash mode in there somehow as well, it would've been the best racing game ever.
Paradise is so good that every year or two I delete my save and start over and it's just as fresh and fun as it was when it first came out and I get addicted and play 10 hours straight.
