I thought I would write this as I couldn't easily find anything on the internet documenting the differences between the original Playstation version of Resident Evil 3 and the PC port. (released by Xplosiv)
The two versions are exactly the same story wise although controlling the game on the PC is slightly more difficult (with very limited gamepad support), by default the game uses the arrow keys as character movement which is unlike most other PC games which use the WASD keys. I always seem to find myself trying to accidentally use them instead of the arrows.
After installation the PC version requires no disc to be in the CD tray, (it's refreshing to see this, as I hate having to look for CD's!) Another of the games changes are that on the PC both the easy and hard modes are unlocked from the start along with all of Jill's extra costumes. (Costumes must be earnt by playing through the game on the PSX version.)
An inclusion that makes the PC version in my opinion easier is the extra equipment available to you straight from the start of the game, the Assault Rifle is already unlocked right from the go even including a full clip of ammo! A list of the extra items is bellow:
- F. Aid Box - With 3 F. Aid Sprays
- Assult Riffle with a 100% clip and 2x extra 100% clips
- Handgun with a full clip and 250 bullets
- Shotgun with seven shells and 56 extra shells
- Magnum with 6 bullets and 24 extra bullets
- Unlimited Ink Ribbons (Saves)
Both versions of Resident Evil allow you to run up stairs without manually having to have the character walk up them, green herbs and other healing items remain (ideas from RE1 and 2) and the option to discard usless items (Used in both RE1 and 2) such as keys also remains in both of the versions.
To end, I also found that the PC version very stable and run well on my Windows 7, 64 bit machine. I couldn't find one fault whilst running the game on Windows, I just wish more controllers had been supported when the game was released. I think that this zombie (see below) wouldn't have been able to catch me if I could use either my wired 360 controller or an old Thrustmaster control that I still use for SNES games. :p
