“Even if a game is making no sales they still need to track those numbers, send sales reports to developers, generate international taxation documents for Canadians like me… etc. And who at WB is going to defend these indie games? Adult Swim Games is gone. To me it’s as simple as ‘Let’s get rid of these niche products made by people who no longer work here which I don’t care about.’”
