The most noticeable difference between the two games is the level of realism.
PUBG does not allow characters to build structures out of thin air or tear down structures with a pickaxe, and you won't find any cute astronaut or John Wick-themed character outfits or brightly colored weapons in the abandoned structures scattered across the maps.
PUBG relies on realistic art and controls to raise the stakes for the player, creating an adrenaline rush that makes each round more exhilarating than the last.
When I'm running from another player in the game, or hiding behind cover, my heart will start to beat a little faster and my shoulders tense, as if the threat were real. Just last night, when I was searching a house for loot, another player snuck up behind me and killed my character with a single, loud shot. I was so oblivious to his presence that when my character yelled and my screen went black, I literally screamed and jumped out of my chair.
The rush makes me a better player and makes the game more enjoyable. If you're like me, and enjoy an experience that will get your blood pumping — think horror movies or roller coasters — you'll probably also like PUBG better than Fortnite.
