But it has always been that way, with first party titles and exclusives , even purchasing studios like Rare or Psygnosis, its not like a brand new situation that developed right after Google announced Stadia.
If Google had done even any research, I would have started by looking at the PS1 launch and how Sony broke into a market then dominated by Nintendo and Sega with their exclusives, they would have secured a multi year pipeline of AAA titles before launch.
This is a mess Google could have completely avoided with some basic research and discussion with the remaining independent studios. Instead they launched and assumed that they could fix this shit later, rather than making an informed decision on if they actually had a real chance.
