Few games have the foresight to tie in stories through their series. However, the rich Resident Evil games manage to do just that by introducing a family of characters--with varying relationships to the famous Raccoon City S.T.A.R.S. team and to one another--that seems to change (coherently) throughout. In Resident Evil 2,
long before we knew how many games there would be in the franchise, patient (almost maniacal) fans were treated to a totally obscure reference. If you search the S.T.A.R.S. office on the second floor of the Raccoon City Police Department, Wesker's desk in particular, you'll get a message that says, "It's trashed. Someone must have searched the desk..." If you choose to keep looking, say, another 50 times, you'll finally receive a roll of film. The film, when developed, produces one picture: Rebecca Chambers in a basketball uniform. Later games in the series will tie in Rebecca's relationship with Wesker more thoroughly, but needless to say, this is the kind of egg that really requires a strict attention to detail.
