Definitely Lego Star Wars (original trilogy of course). My brother and I played it almost endlessly on our PS2 when we were children. Later on we got it on both PS3 and 4, and I even bought it in steam a few years ago for the nostalgia. On the computer I naturally use my PS4 controller for it.
I try to say it when I have something to say though. I didn’t always bother on Reddit.
