The Mako Reactor says: If youve already played the game on the PS4 or Xbox One, theres no reason to bother with it on PC unless youre interested in checking out its mods which do everything from altering how characters look to unlocking gear. With Capcoms stance on Monster Hunter World being that mods arent officially supported, it will be interesting to see if Iceborne will allow these user creations to flourish as they did with the base game.
