Video games have transformed the UEFA Champions League into something much bigger than it is.
It's only a continental tournament as the CAF Champions League, no one is 'the best of the World' for win just that.
the Champions League is the highest quality of football the world has to offer. Any given forward has to go against the world's best defenders and vice-versa. There's no shitters from Aston Vila or Sporting or Arsenal playing in that final like you would find in Euro/WorldCup/Copa. It's the absolute pinnacle the sport has to offer. The only reason the World Cup is stll important is because of history, but the Champion League will replace its importance within our lifetime.
