You don’t need a Stadia controller or a Chromecast Ultra. You can play on your PC or any Chromebook or Android phone using keyboard and mouse or any plugged in controller. I just tried it out on my PC. It’s only 1080p but it runs at a steady 60 FPS, something my Xbox One X doesn’t do well. 4K 60FPS is doable with an Xbox Series X or an RTX 3080… Gearbox needs to work on their optimization, LOL. BL3 has the worst writing of the entire franchise, but hands down the best gameplay and gunplay. Even if you only play single player, this game is an absolute bargain for $ 10.
