What impressed me about RE3 was the few new concepts that sort of distinguished itself from the previous RE's. The first thing was that this game kept you nervous. Once you thought you were safe from those monsters, that Nemesis pops up and keeps chasing you around...a real adrenaline pumper. Up to the end you're thinking, "My god! He's still alive!" There's another little feature that's kind of like a "decision-making" concept, where you actually are given a choice of what your next move is (like multiple choice)...to me it's ridiculous, but it is different.
One minor detail, though, that sort of...well, it didn't bother me, but just kind of made me think how ridiculous the RE3 artists' minds were when they designed Jill Valentine in this series. I mean here's an ex-cop who used to be on an elite force unit, who is now in the middle of a zombie-infested town full of blood and gore, running around in a mini skirt and a tank top or whatever you call those kind of tight shirts. I just kept thinking, "Oh, Lord...they may as well ... made her wear high heels." Come on...let's not cheapen the image of the mighty hero ofRE1 by making her look like a ditzy bar waitress.
