The general goal is to always nurture newer players until they’re good enough to take on the veterans. Retaining new and casual multiplayer audiences is an ongoing challenge for any game, whether you’re Age of Empires or Rainbow Six Siege. Anyone who’s been sticking with the scene since its original release back in 1999 will be pretty good at the strategy game by now. But with the initial HD re-release in 2013, followed by Age of Empires II: Definitive Edition in 2019, new players are likely to have come to multiplayer circuit, ones that won't have the benefit of over 20 years play time.
With an RTS game as mature as Age of Empires 2, competitive play is no joke.
