Well, it's nothing big, just something I've always wondered, but couldn't be arsed to join a Resident Evil forum to find out, as it's not that important to me. Anyway:
In the restaurant when you meet up with Carlos, you get a firehook so you gain entrance to the basement of the restaurant(This also triggers an appearance by Nemesis.) However, what's the purpose of this basement? I went down there and there's absolutely nothing there. The only purpose I can find is the triggering of Nemesis. And I could've easily avoided using the fire hook on the entrance and skipped the whole scene. Or is there something I don't know?
Also, doesn't the opening part in The Mercenaries remind you of the movie "Saw"? With the voice that says "The rules are simple", and the text saying "these people have forgotten what fear is, it's time for them to remember." I have a feeling the makers of Saw has been playing Mercenaries.
