I've seen the private -> public transition ruin many companies, and it makes me sad. I'm holding out for Valve but I imagine that if they ever go public that'll be the end of my game purchases, unless a worthy competitor arises.
Valve barely makes games anymore. Are you referring to the steam platform in general somehow getting bad/worse than competitors?
Yep I'm referring to the platform itself. I wish Valve made more games, but I'm happy with the direction they're going in, i.e. working to make SteamOS3 and their Steam Deck a success, since this will also be a win for Linux gaming.
