1st already has beta version working with Dota 2. Not sure if you've ever played Dota 2 but I've been playing it for years. The quality of the game isn't affected on the platform, the platform just allows wagers to be made on the matches, and the resulting payouts for the wager are fulfilled via smart contract through the 1st platform using 1st token. They plan on adding Counterstrike after Dota 2 platform is released to the public. Hope this helps!
