I'm unsure what I'm going to do when my steam controller breaks. No other controller even comes close, including the Xbox controller that I consistently see recommended. The gyro especially is so fucking nice, and AFAIK nothing else has one that works the same way.
I can't believe people shit on the controller when it was released, they had no clue.
I think it had to do with the touchpads introducing a learning curve. Tbh I think if they decide to redo it then they should add swappable physical modules, so you can literally swap the touchpads for a stick/d-pad, or trackballs, or whatever fits. I can't remember if they patented that or just had a prototype with it, either way I thought it was cool and was kinda disappointed it didn't make it into the final version.
