Play the odd single player game from time to time. Having a go at doom eternal at the moment.
But nothing will ever compare to prime ET. Even though OZ's prime was way past the game's competitive prime, still was so much fun. The community, drama and laughs were lightning in a bottle from about 08 when I started to around 2012. It started to get steadily worse as the number of players dropped.
Overall though, ET is a special game, conceptually simple and yet so dynamic at the same time...
