Diablo 4 officially launches for everyone on the 6th, but early access released yesterday for Twitch streamers and people willing to pay Blizzard a premium to start playing it early. It's good so far, but I'm not very far into it yet. You can check out SkillUp's YouTube review here if you want more detailed information about it. https://youtu.be/_Vk7yrh_JhM
I tend to play different games on a rotation based on what I feel like playing, so I tend to bounce around a bit.
I primarily play games on PC. I have a Switch that I use every once in a while, and I recently bought a Retroid pocket 3+ for emulating games on a handheld.
