Contested Sequel: L.A. Rush was seen as a step down because it focused more on reality than insane stunts. Reviews were mixed.
Crowning Music of Awesome: All the tracks in Rush 2049 especially the arcade and Dreamcast versions, too bad on the N64 version you have to use an expansion pack to hear music in races, shame *runs to get an expansion pack*.
"Headthumpin'" "Amiga-ish", "Doin' Time", and "High Roll" from Rush 2, and "The Rock" from the arcade Updated Re-release of the first game.
Also, "What's Your Name?", the music that plays in the first game when entering your name on the high scores list.
Let's not forget "Zethno" from the original. Say what you will about the rest of the game's soundtrack, but that particular song kicked ass!
Ear Worm: "Rave Rush" and "What's Your Name?", two tracks from the original game.
Track 5 of N64 San Francisco Rush (Track 6 of Rush: The Rock) features a tunnel shortcut with an inexplicable pit of magma and spikes that will kill you if you don't expect it and angle your car properly to make the jump.
The fog color cheat offers some very eerie color options. Want to enjoy a drive through San Francisco with its signature fog turned blood-red?
For environment-conscious players, the Los Angeles track in Rush 2 replaces the fog with smog.
The "Killer Rats" cheat in Rush 2, which turns the otherwise-harmless mice in the New York subway shortcuts into ferocious (though thankfully stationary) entities that blow your car up on contact.
Porting Disaster: The notoriously bad PSX version of the first game. To elaborate: Really long load times (as much as 30-45 seconds between races), low framerates, ugly textures, only four tracks instead of six from the arcade and N64, questionable physics changes (most importantly, the cars had too much gravity, meaning the long air time from the arcade and N64 versions was significantly reduced), and completely replaced music.
Rush: The Rock suffered from this twice. The version included in Midway Arcade Treasures 3 has mostly every sound replaced with something more annoying, including the soundtrack (the PS2 version's sound is also very glitchy - being played back a quarter step lower than the Xbox version, while sometimes clipping songs short and playing random songs in their place). There was also a native PC version (which you'll really have to look around for), but it has very awkward controls and its draw distance is screwy to the point that it displays both high and low LOD models for certain track props. That, and your opponents are always similar. The worst part is that these two ports are the only non-arcade versions of the game.
Track 5 in 2049 can be summed up as "right-angle hell". It's not an unfair course, but it requires a lot of technique and slowing down compared to other courses. Once mastered, it's easily one of the most fun tracks in the game.
