Steam Deck. I haven’t been this excited for a console since the original Xbox. I play a lot of games that I would otherwise avoid on my gaming rig, and it’s excellent for traveling.
Steam Controller. This one was worth the effort to get used to, and it introduced me to gyro controls and paddle buttons. Also, it was integral to the Steam Deck’s control scheme design.
Least favorites:
Wii. There were a few good games, but the controllers sucked ass. GameCube was better.
Game Gear. Screen was a smudge-fest. Any kind of motion was super hard to see.
Gen 1 Xbox controller. That thing was massive and awkward.
