If you're one of those players that like to explore all the little details of the glorious mansion in the R Emake, you'll find that several photographs and pictures have been removed from their frames; one in praticular was removed after the glass was smashed. You wonder why this is the case and then once you realize who the traitor is, it makes perfect sense; Albert Wesker may have been in several of those photographs and just to keep his cover for as long as he could, removed them all.Magnificent Bastard indeed.
The original Resident Evil. Forrest of the BRAVO team has been pecked to death by crows. If you're playing as Jill he has a grenade launcher lying next to his corpse. This makes perfect sense (and not just because the crows in this game are vicious, overpowered bastards): have you ever tried to hit a crow with a grenade launcher? Assuming Forrest even bothered to try shooting them, he would have just missed time and time again. Of course, if you're playing as Chris he has a clip of handgun ammo next to him instead, but let's just ignore that little incongruity...
On reflection, it's actually just as interesting from Chris's perspective as it was from Jill's. Forrest has a clip full of handgun ammo - but no handgun. He was trying to attack these fast, agile enemies with his fists or his weak knife. Even if he managed to hit each crow repeatedly, it wouldn't have done him any good...
The game's infamous translation is actually a case of brilliance when you realize that it contributes to the whole b movie feel of the early games.
At first Barry's famously cheesy line of "It's a weapon! It's very powerful, especially against living things!" in reference to the acid grenades just seems like another case of bad translation. Until one stops and realizes that acid rounds are highly effective against enemies like hunters and Yawn, both of which are living things compared to the zombies that dominate the game early on.
Why is Enrico ready to aim his weapon at Chris but not Jill? He may only know the gender of The Mole.
Why does the mansion have so many typewriters? A quick glance at the dates for some of the files are dated from the 1960s, a time where typewriters were most likely quite common when the mansion was built. Even in 1998 (which is when the game takes place), typewriters were still in use, though they weren't as common thanks to PCs quickly becoming popular. Since the next two games also take place in the same year, it is also not unusual to see typewriters in places like the R.P.D station or the newspaper headquarters.
