If you're one of those PC-only gamers, you haven't played Resident Evil 5 yet. You'll get your chance this fall when Capcom releases the PC version. But if you're not one of those PC-only gamers, odds are you've already played Resident Evil 5 and shouldn't bother with the PC version.

Or should you?

After the jump are the three reasons you'll want to replay Resident Evil 5 when it comes out on the PC.

0) It uses Games for Windows Live

Given the pain in the butt Microsoft's Live front-end has been for many PC gamers, I'm not convinced this is a reason to want to play Resident Evil 5 on the PC. Maybe it should be a warning. But it's there, so it's worth bringing up. It's how you'll play multiplayer co-operative games, which are a big part of Resident Evil 5's appeal. And, if you care about achievements, the PC version's are separate from the Xbox 360 version's. Maybe this is a reason to want to play Resident Evil 5 on the PC after all.

1) It's in 3D

If you're one of the early adopters who shelled out $200 for a pair of Nvidia's 3D glasses, I have two things to say. First, ha ha. Second, here's one of the rare games optimized to take advantage of Nvidia's 3D tech. The only hardware requirement (expensive glasses excepted) is a display that can handle a 120Hz refresh rate.

Having played the PC version of Resident Evil 5 while wearing these glasses, I can see the appeal. Yeah, it's a gimmick. But it's a fancy gimmick that gives the game new depth. The bullets spray out of your gun on their own plane. A monster dog's head splits in half on another plane. A zombie lurches on another plane. Chris Redfield enormous biceps bulge muscularly on another plane. Sheva gets in your way on another plane. A chucked hatchet tumbles towards you through all these planes. It's a grand presentation of hi-res Resident Evil 5, gratuitously layered like an elaborate cake. It might be entirely made of icing, but it's still an elaborate cake.

2) It uses a keyboard and mouse

Let's state the obvious: headshots are much easier on the PC. In fact, I'm convinced this is going to make the early going a lot less frustrating. But is it going to mess up the difficulty level? Am I going to be getting an accuracy rating of "S" on every level?

One difference I'm not so fond of is the way mouse and keyboard controls turn off your aiming laser. When you're using a gamepad, the aiming laser did a great job representing distance and line of fire. But with a mouse and keyboard, you get a conventional flat reticle superimposed over the screen.

The keyboard supports anything you want to do. Quick turn with the tap of a key. Shake off zombies that have grabbed you by smacking A and D wildly, like so: adadadadadaddadaaddaddda. You can more quickly interact with your inventory using the mouse cursor. Furthermore, the number keys are bound to each of the nine slots in your inventory. This means every inventory item has a hotkey. You don't have to pick and choose which items sit in the four d-pad slots.

3) It will have "bonus stuff"

Capcom promises the Versus mode will be part of the PC version, but there's no word yet on whether it will ship with the game, be available later for free, or be available later for a fee. As a huge fan of Versus mode, I'm looking forward to playing this on the PC. It's a wonderful alternative to the usual shooters and it has a sort of cerebral dimension that will appeal to PC gamers. Wait, did I just call console gamers stupid? Oh snap! I've just insulted myself.

But beyond Versus mode, there will be new content for the PC version. "We're doing some bonus stuff for the PC version," says Capcom representative Chris Kramer from behind his Nvidia 3D glasses. We're looking at each other, each of us behind our big green glasses, having a conversation and only slightly aware how ridiculous we look.

"What kind of stuff?" I ask from behind my $200 shades. The batteries seem to be running low as I'm experiencing bright white flashes. Maybe it's menopause. Can dudes get menopause? "New maps? New modes? New creatures? A new chapter maybe?"

"Bonus stuff," Kramer says, and leaves it at that, because either he doesn't know or it can't be announced yet. His big green glasses make him extra inscrutable. Fair enough. It's not like I need any excuse beyond higher-res graphics and a mouse and keyboard to replay Resident Evil 5. But whenever Capcom wants to tip their hand about what sort of bonus stuff we're getting, I'll gladly get even more excited.
