Resident Evil 4

The story takes place in Spain, and the Spanish spoken by the villagers in the game is called Castilian (which has a different pronunciation than the standard form of Spanish, known as Español, commonly spoken by many Latino). The currency used throughout the game is the Peseta, which some may find curious, as Spain had switched to Euros in 2002, and the game takes place in 2004. But this may have been done to show how behind the times the area is compared to the rest of Spain, due to its remoteness and its inhabitants being afflicted with the "Plaga" parasite, transforming them into, essentially, mind-controlled puppets. As such, it would make perfect sense for them to still have the older currency in their pockets, etc., because they've all been in their "puppet-like" state for at least two years.

During the scene where an armed helicopter assists Leon in cleaning out the bad guys, the helicopter pushing over the fuel tank doesn't make a sound until it is revealed by the camera. The Ganados are alarmed only by the creaking sounds of the tank. The helicopter makes so much noise that they should have heard it coming long before it arrived at the tank.

During the end credits, slides are shown of the village in a happier time, followed by what happened when Las Plagas were introduced.

Ported onto the PS2, in addition to a reduction in lighting and detail, the polygon count was toned down. Also, all of the cutscenes in the PS2 version are FMVs (meaning, they are pre-rendered and therefore don't take into account any recent changes made to the characters or areas, such as costume changes, blown up barrels and doors with bullet holes). On the plus side, there's an extra mini game called "Separate Ways", which is a five-chapter storyline that follows Ada's actions during the main game and also addresses some unanswered questions such as what happened to Leon's jacket and how Ashley met Ada.
