Monster Hunter: World launched with 31 monsters. The fact that they are variants is irrelevant, as it still counts as a monster. Siege hunts are still considered hunts. On the other hand, Monster Hunter: Wilds has 29 monsters, 2 of which (🧸Zoa Shia and Guardian Arkveld) are single hunt monsters that you can't hunt again. They aren't around 10 fewer monsters as this article claims, but rather 3-5 fewer, depending on whether you count Zoaಌ Shia and Guardian Arkveld as roster-worthy.
