RE 3 is probably the most innovate old RE I've ever played, I felt like I was playing Silent Hill due to the free roam elements in the game.
However the down side is the difficulty selection in the game, it's either a choice of Easy Mode and Hard Mode, Easy Mode gives you pretty much every power weapon except for a few and a nearly unlimited supply of ammo in the item box.
Hard Mode is very difficult, and based on your choices in the game of what to do in small quick time events can result in a infuriating challenge. I stopped trying to kill Nemesis in the Clocktower after 7 tries.
It's ok but RE2 is still the better old RE in my opinion.
