The Good: Decent story, tons of gore, great graphics and audio, new features are neat
The Bad: Abysmal combat, terrible control, extremely slow pace, laughable voice acting
I tried so hard to love RE1 and look beyond its major flaws; Flaws such as the abysmal combat system. You can't aim at anything! The tank controls don't help either, so you always end up dying CONSTANTLY, and with a lack of health and ammo you'll toss your PS1/PS2/PS3/PSP out the window. The other flaw is the level design. Everything is so confusing and it's so easy to get lost. The map doesn't help one bit because all it does is highlight the hallway that you are in red and you have to decipher what doors go where. Another thing that doesn't help is the game's pace...its sooooooo slow! When you open a door or walk up stairs the animations talk forever to finish, menu are slow, text is not skippable. Another flaw is the laughable and hideous voice acting. They actors sound like they're fresh out of remedial drama, while the live action cut scenes are just as bad.
The only good part about RE is the story, enemies, and the amount of gore there is. While DC offers vibration, uncensorship, and a few game play tweaks it's not worth it. RE4 was my first RE and going back to this is just awful. If you haven't played RE1 you're not missing much at all.
