Uncertain legal regulations with crypto so I could see  Valve shying away from such games. There could  end up being tax reporting requirements that Valve would have to upkeep and send to users. We're seeing this now with exchanges and wallets like coinbase that offer interest on your holdings.,(reply>), @Naud van Dalen There's actually been a funny similar case in another game. Not pirated, because it was a free game. But there was a cheating tool going around  that had a crypto miner in it. So anyone who wrote a negative review complaining about the game crypto mining were basically outing themselves as cheaters.,(reply>), @nul A smart idea would be implementing crypto miners in cracked games, so you earn money off of pirated games. Then they can't complain because they didn't buy the game.,(reply>), And there's been a few games sneaking in crypto miners without the user's consent.,(reply>), Could also be the environmental impact of nfts and cyrpto too valve could get a huge blame for it
