An interesting perspective, but there are a couple of factual errors present which may invalidate the premise.

Starting from the most obvious, the only cube with a heart, and the only cube personified, is The Weighted Companion Cube in the level where you, the other cubes in the game are Weighted Storage Cubes, and are used both before you receive the Weighted Companion Cube and after you incinerate the Weighted Companion Cube.

Secondly, on the turrets, they can be defeated via a brute force approach (in some cases requiring speedy running towards them in order to get behind them before they gun you down, in other cases using a cube as a shield and knocking them over with it. And then there are those where your best bet for defeating them is to manipulate energy pellets, which in the levels they appear are usually your only means of progressing, and are very much the main male imagery of the game; if we go by the primitive Freudian analogy of the shape of the portal, they're very much a phallic symbol and require you allowing their emissions to enter into your portal in order to progress)

Those are the main factual problems I think are present in the article, but there's one more issue the article has - The assumption that a character in third person is an external entity who is a puppet while one in first person is an identifiable character the player embodies, and the amount of games with male third person protagonists which would mean that those few with female third person protagonists are under your metaphor the female objectification exception to the male objectification norm.

The reason I take issue with this assumption is that, if I recall the evidence I've seen correctly, it is more typical for players to not consider first person (or second person in the case of Interactive Fiction) characters in their own right, and so are more literal 'puppets' to the player to be manipulated, while third person characters tend to be more typically considered characters in their own right rather than simply a means of manipulating the virtual world the game takes place in via manipulating a puppet within that world.

RE: cerdoenbrama - What's wrong with mental jerkoffs? They're fun and healthy, just like physical jerkoffs. (Yeah, I'm fond of the concept of Death of the Author. Provided no-one pretends that this sort of thing is intentional on behalf of the author without going by Word of God evidence, then I start getting tetchy about them)
