Honestly, one of the best things about Arcade is how easy it is to get playing. Having to boot up my gaming pc or PS4, being bombarded with OS updates because its been a while, having to download patches for games etc has really put me off of gaming lately. Arcade gets rid of all of that basically with automatic updates and in its app-like nature (+ because it runs on the devices I use each and every day). The welcoming art styles and easy-to-pick-up gameplay of the games is just what fits my needs too. I was extremely skeptical when the first early impressions (way ahead of its launch in the Apple internal beta) came out, but I'm really enjoying it.
All I need is that new 128/256 GB Apple TV refresh lol, only got 1 gig left and I don't want to accidentally purge my infuse meta data :(
