Already "stole" the ping system from Apex, that was quick
The upside and downside of Fortnite. They copy everything that is popular and liked. This game is like market research 101. It was being made as a co-op zombie shooter (a huge trend a couple years ago) with building elements Ć la Minecraft when that was the big thing. It turned into mainly battle royale when that was the thing thanks to PUBG. It has/had everything in terms of monetization: lootboxes, battle pass, daily and weekly login bonuses and challenges, emotes, sprays, custom skins and models, weapon skins, companion pets. When Realm Royale showed a superior location pinging system, they instantly took it. Apex has the best pinging system? Few weeks later it's in Fortnite already. Sea Of Thieves is having a resurgence? Let's throw in the pirates, the mancannons and the similar designs. They only do cross-promotion with the biggest names like Marvel or Marshmello for maximum reach. All or nothing.
On the one hand, they're incredibly effective at finding what their userbase is looking for, immediately creating said content, usually without major hiccups (there have been balance issues and glitches in the past, but usually relatively small things). On the other, you'd be hard pressed to find a single element in Fortnite that was not directly lifted from some other widely popular game. But again, from a technical standpoint there is not much to complain about: they delivered an accessible battle royale with cross-play and cross-progression, one I can pick up anytime with my newcomer buddies and have a great time with. Playing something like PUBG with newbs is a chore, on the contrary. Ultimately this is good for those already invested in Fortnite and not planning to leave, as other games' innovations will inevitably land in Fortnite too sooner rather than later.
