I was talking to a couple people about it a couple nights ago, but PC gaming goes through shifts in popularity. 5ish years ago, the survival sandbox zombie/alien/monster genre was HUGE. DayZ really kicked it off. After that, everybody tried to get a piece. WarZ, Project Zomboid, 7 Days to Die, Rust, etc.
The shift before that (and still current lol) was WoW clones.
Now, it’s Battle Royale games and/or mods. Started getting steam with PlayerUnknown’s Arma 2 & 3 Battle Royale mods, got more popular with H1Z1: King of the Kill and then burst onto the mainstream with PUBG. Fortnite has been a solid alternative and there will be more BR games to come.
That’s why… Rock n Roll Racing Online is a lock, IMO. Or World of Diablo/Starcraft.
