Yes, this one. It's obviously super dated to the point of it seeming more like a parody than the main intro of a horror game, but as time went on I think this intro has done nothing but get better. Nowadays I doubt many people consider RE1 a horror game still (or at least a scary one), but as the series has fully embraced the horror instead of the horromedy style of this game, it's super fitting now (it doesn't stick out that much now either, thanks to RE5 and 6).
Of course, it's still corny and ultimately fails its purpose of setting the mood for a horror game, but then again you aren't playing Resident Evil 1 nowadays to get spooked. What do you think about the intro?
