Why is that?
Because it's a setting where women literally throw themselves at Geralt (the player) in exchange for services (or for sometimes no reason at all).
The big one for me is the card collection, however, which plays into gamer tendencies to complete tasks given to them. By creating the card game for having sex with women, it explicitly makes every woman in the game a potential target, with the player wonder if there is a card for this woman, and what would it take to get this card. This is not a good thing because it then implicitly objectifies the women as being something to be accomplished - it was a goal to go and have sex with as many women as possible because the game will reward you with a type of content. Kudos to the women that find it silly (there is one on this board), but it actually made me feel uncomfortable because I didn't like the message the game was sending me and how my gamer mindset was originally perceiving it.
Even the second one jumps straight into the male gaze, with Triss being completely naked while Geralt is not.
And the false equivalence thing, how can someone differentiate between that and a 'power fantasy'? The comic implies that women have a standard opinion of what is considered attractive. The 'false equivalence' only exists on a personal level, if you don't agree with the comparison (which is fine). But then how can one claim to know what men like and women don't?
False equivalence doesn't exist on just a personal level. Yes there are personal preferences, but there is also the aggregate of all the people within a society and what they do and do not like. The men that are voted the most attractive (in the West) are typically not the muscle bound, square jawed type. Arnold Schwarzenegger and Sylvester Stallone were huge in the 80s but not really known for their sex appeal, while people like Tom Cruise and Patrick Swayze definitely were. Yes those two are still physically fit (there's an evolutionary biological motivation for this too), but there's still the trend.
Not everyone is going to find Scarlett Johansson attractive, but it doesn't mean she isn't typically considered one of the more attractive women. Robert Pattinson is very often one of the top (if not the top) attractive male celebrity.
Toss out some pictures of Justin Bieber or Robert Pattinson to a typical crowd of men and a typical crowd of women, and see if there's any measurable difference in how the rate the attractiveness.
That's not to say there isn't overlap, especially as very few human beings meet "ideals" that can be established in video games, but the musclebound Batman isn't being drawn like so to be appealing to women, while Wonder Woman definitely leverages the male gaze.
The issue, of course, is when this becomes so common place that people no longer even notice it.
