Sure, some of the comments are a bit harsh, but perhaps only because they come over as direct attacks claiming everything looks terrible. I can't speak for the others, but I know that I don't want to see most of these items in-game because after the cow mangler and bizon, I'm seeing the effect of drastic changes in the art style.
Personally, I don't want valve to implement these weapons in-game because of the art styles not blending well. Perhaps they would be better fit in a sort of total conversion, where the entire setting of the game is medieval, with new character models and perhaps redesigned maps.
I'll be the first to say that I wish I could make models like those seen in the pack. They're all very nicely done, though not all are as clever or ingenious as others, but it just... doesn't fit.
I commend everyone who worked on the update, I don't think I could do it just yet, but I hope no one loses any sleep over the idea that I won't use them because I prefer the 1950s setting.
