CS2 > OW2 > VAL (from hardest to easiest)

CS:GO/CS2 is a 12+ years old game and therefore already has a well-established professional scene. Breaking through would be near impossible under realistic circumstances. Same thing for OW/OW2; it's an 8+ years old game and in my honest opinion is a harder game to learn than VAL. I'd say VAL is the easiest of the three to go pro in simply because of its age, popularity and it being a tactical FPS. There are leaderboard grinders in the T1/T2 scenes so that's that. I've personally played with two players that are/were in T1/T2, players that were considered "nobodies" before Valorant's release and they've made it since. I know for a fact they'd make it again even if they started playing today

Kindness goes a long way in every aspect of this life. There are ways to word things so that people are more receptive as it then falls under constructive criticism rather than toxicity
