I've been playing ARK: SE since early in the early access phase. I've had ark: SA for a while, but due to running Linux on some older hardware (nvidia 1660 GPU), the performance was terrible. Since the update to unity 5.5, i've also upgraded my hardware (now an AMD RX 7700 XT), making performance acceptable - not quite as good as ARK: SE, but the graphics and QOL features or much better in ARK: SA, so I'm here to stay!
