Oh man, power halberds? I absolutely adore this.
Fantasy games make this mistake all the time
Well, there's another layer to this: very few of these terms actually have a historically consistent meaning. Most of these european terms were used over the course of several hundred years, at least, and over the course that time the weapons they referred to changed frequently. When you add language barriers on top of that, weapons being exported from France to Switzerland to Germany to Austria and taking their names with them, and you have a total mess.
I have absolutely no doubt that, at some point in time, someone held a weapon very much like this one and called it a Halberd. It's a bizarre kind of arrogance for us modern folks to insist that he was wrong to do so. The idea that these terms represent specific weapons that can be described precisely is a modern concept that people have (unsuccessfully) tried to retroactively apply.
The lesson is that you just shouldn't worry about it, because medieval soldiers certainly didn't.
(Another random entry in this category: "Dragon" and "Wyvern" are not words with actual zoological definitions, and anyone who tried to insist you use one or the other on the basis of number of legs or whatever is deeply misguided.)
