Now, I've never been much of an internet person, so while I'm sure this has been discussed already on several internet forums, I have yet to participate in one. So I ask again.

Why exactly does JC keep the sword on when he stores it on the inventory? And not just that, he also turns it off after taking it from under the coat just so he can turn it on again on screen.

I also think we should skip boring answers such as "making a sword that good take only 1 space on the inventory would be too OP". Sure, that's probably the real reason, but it's more fun to come up with crazy theories like "It's cold and JC needed a in-coat heater"

The Dragon's tooth sword emits a shimmering blue light. JC simply keeps the sword on in order to see the other stuff he keeps in his nano-augmented backpack that we mere mortals call "inventory".

Example:
*JC is hiding in a narrow and dark ventilation shaft.*
JC: -Where did i put my GEP gun?"
*Fumbles in the dark but still manages to open his backpack, blue light emits from sword inside of backpack.*
JC: -Ah! There it is...

The explanation I've heard is that the developers made that "turning on" animation before they were really solid concerning how the sword worked, and it just... stuck around. Regardless of explanation, there's definitely a bit of a contradiction there.

The backpack/coat were he curries must be pretty thick, too, or the light would filter out making his "hide in the shadows" stealth tactic useless.

... Unless DX guards are like the ones in Splinter Cell and can't spot the light moving right in front of their nose, that is.

Never noticed that, I guess I'm not as nitpicking as I thought I am. hehe

LOL! Oh, I LOVE this explanation.

Quite hilarious, sir, and very original. And I love the choice of the GEP gun.
