For me, it's definitely CS:GO. It's also probably the best game for non-gamers to watch competitively. You can explain the game to virtually anyone in 5 minutes

For me, it's definitely CS:GO. It's also probably the best game for non-gamers to watch competitively. You can explain the game to virtually anyone in 5 minutes, and it's easy for a beginner to see and appreciate when true skill is on display (kills, aim, coordination, etc.). A truly entertaining game to watch imo.
