I don’t know if (a) it’s real and (b) it’ll be like the original Steam Controller, but if so, the point is that it’s the most-viable mouse alternative that you can have in a gamepad form factor.

If a game can be played with a traditional gamepad, then sure, there are a bunch of good options. But not all games are like that.

The original was useful for someone who wants to play a mouse-based game on the couch.
