Duh, people are pissed at corporate greed that’s is at the core of all cease and desist orders on fan projects. Be it from Nintendo, MS, Sony or Valve and they aren’t stopping.
Indie devs need to stop wasting their time and efforts on fan projects that will never be played by the public because of these corporations shutting them down.
Instead of wasting 300+ hours making a fan project with nothing to show but the knowledge and potential lawsuit you’ve gained, how about putting all those hours into a personal project that is inspired by the games you want to copy instead.
You could make the next Portal, Team Fortress 2 or Hit and run. Just name it something different and stop making 1 to 1 reproductions of corporate property.
