Resident Evil isn’t a simple action game. Most of the time you have to conserve your shots and just try to survive. The limited number of rounds for your weapons actually helps to create a feeling of terror as you wander through the mansion, your ammo supply getting lower and lower. You frantically begin searching every bookshelf and closet for more ammo in anticipation of your next encounter with the undead. You gain access to different areas of the mansion and its grounds by finding keys and solving puzzles, using your head and your guns. The puzzles in Resident Evil are pretty logical. For instance, at one point you’ll face an impassable giant mutant plant. You simply go to the garden and get the weed poison. It’s all really straightforward stuff.
