Though from what I read, EA allegedly had zero input into Apex. That might be why it is becoming popular. I just tried Apex a few days ago, it was pretty fun.
"Of course, Titanfall 2’s disappointing sales aren’t as much to do with the nature of its content as much as it is about timing, and that’s entirely on EA. Sandwiching Titanfall 2 between Battlefield 1 and COD: Infinite Warfare hasn’t helped the game at all. Seriously, what were they thinking? Apparently, even the game’s producers were left in the dark behind the decision-making process."

It's multiplayer was good too, but it was launched in a really bad spot that was 100% EA's fault.
