The Simpsons: Road Rage (Game Boy Advance)

It's Crazy Taxi! ... starring The Simpsons! ... on Game Boy Advance!

A decent game on the consoles becomes very hard to play on the GBA, as everything is flat and it's hard to tell where the level boundaries are.

Regional Differences
While the American version was released after the European one, the latter has a bit more polish.

Intro
G3G2U7cIZcE

The European version has a fancy intro, while the US version just goes straight to the title screen.

Locked Level
In the US version, locked levels are displayed with the word "LOCK". In the European version, it's an actual graphic of a lock.
