Agreed, OP.
It is the trend that bothers me (i.e., that it still is a prevalent trend, particularly in fantasy type games) to present women in overtly sexualised ways without any kind of justifiable context. That is not to say it is wrong for female characters to be designed to look beautiful, just that doesn't and shouldn't often come with skimpy atire. I things have improved in some games - i.e., Gears of War 4 - but still lags in others (FFXV...but this was even more for the portrayal of women characters).
Just to be clear, I don't have a problem with the portrayal in stuff like Horizon. I mean she has a couple of costumes that skin, but I don't see that in itself as an issue, because (1) she is portrayed as a consistently capable character, (2) she has a wide variety of atire, (3) girls do wear clothes where they show their belly for instance, and it can look good - there is no problem with that if the context isn't purile. It is context dependent.
