The Steam Controller has a bit of a learning curve for some. I recommend playing anything you're comfortable with. Something with good mouse support, so you can experiment with the touchpad and eventually gyro. Any shooter (1st/3rd) with good mouse support should be good.
Reconfigure controls so you can keep from using the face buttons as much as you're used to. Putting things like Jump/Run on the paddles can go a long way.
And a happy belated birthday to all that I have missed in recent months. I won't go into great detail for my absence since the most important thing is that you all had great days and were able to celebrate and enjoy your day to the fullest!
Thanks everyone for your greetings! was a great day, a friend gifted elder ring and a lot of clothes. yesterday in Chile we change our timezone so i was working in the night validating the change. really really thanks for all the greetings and love!
