Resident Evil 3: Nemesis is as excellent as it is scary, and it is very scary. Take it from someone who doesn't scare easily - Capcom pushed the boat out on making this one pure paranoia fuel.
While the zombies can sometimes be annoying, the overall experience is just as good as Resident Evil 2, which was already amazing, and adds more tension. Also, the new Jill Valentine is just too darn likable.
