Concerns about weapon design similarity in Monster Hunter Rise (Wilds is likely a typo) compared to Monster Hunter: World have been addressed by Director Yuya Tokuda. While World weapons often shared a base design with variations based on monster materials, Tokuda confirmed that Rise's weapons boast unique designs.
This directly counters concerns about repetitive weapon appearances. Although some World weapons became unique through upgrades, many remained visually similar. The image below illustrates this, showcasing the similarity between certain upgraded weapons in World.
