For me it's Portal , I also love that a game that's focused on gameplay & taking advantage of controller features like Astro Bot is getting high praise . I'm happy that a MR headset is finally mainstream thanks to Quest 3 even if it will be some more years before it's great . I'm happy that Sega is looking into cloud gaming because I feel they will use it like the Arcade era & actually make games for the cloud that are not playable at home yet.
Happy that we're moving closer to the Digital Locker era but I worry about the hit the industry will take in the transition
