Cloud giant Oversized Weapon (Ex) question

[Firewarrior44]

The Cloud Giant ability Oversized Weapon (Ex) States : " A cloud giant can wield Gargantuan weapons without penalty. Most favor the use of immense morningstars."

Does this mean that a Cloud giant can wield a gargantuan two-handed weapon such as a gargantuan Greatsword even though it's size category exceeds a size of weapon that a creature of the Cloud Giant's size (gargantuan) can normally wield?
Or does Oversized Weapon (Ex) simply remove the penalties from weapons which a Cloud Giant could normally wield i.e. gargantuan Long sword?

Is it the same case for a Tiefling with oversized limbs?

Oversized Limbs : "You have over-sized limbs, allowing you to use Large weapons without penalty"

[Nefreet]

I believe so, because it's the exact same language as the Redcap ability, and it's a small-sized creature wielding a medium-sized two-handed weapon (a scythe).

[Pheoran Armiez]

I agree with NeFreet. The rules do not make mention of light, one-handed, or two-handed weapons. It states ALL gargantuan weapons. Proficiency is another story, but as a GM I would rule a cloud giant could wield gargantuan weapons as if they were sized for the giant.

If it states "without penalty", that includes both the penalty to attack rolls and the "penalty" of size step-up (light is treated as 1-h, 1-h as 2-h, 2-h as unwieldable). Redcap sets the precedent so any ability that mirrors the verbiage used also mirrors the mechanical results. This includes Tieflings with Oversized Limbs, Ogrekin, Half-Giants, etc. By contrast, the Titan Mauler's Massive Weapons ability singles out "penalty to attack rolls" which means it has no effect on the effective effort to wield but only reduces the -2 attack roll penalty per size category difference. However, Oversized Weapons only affect Gargantuan weapons so you cannot have a Huge Cloud Giant wield a Huge Greatsword as an Undersized weapon in one hand because it is a Huge Greatsword rather than a Gargantuan Greatsword. So he can wield a Huge Greatsword as a 2-h weapon and also a Gargantuan Greatsword as a 2-h weapon, but a Colossal Dagger still counts as 2 sizes too big and is treated as a 2-h weapon with -4 to attack and he cannot wield Colossal 1-h or 2-h weapons at all.

I assume that basically yes, it was intended to work like the Tiefling's oversized limb ability.
