I have a funny/pathetic story regarding SSX. I literally injured my right thumb playing the first SSX game on PS2. I had to do physio for it, it was ridiculous.
I used to hold my controllers with my right index finger hovering on the square button, middle finger on the triangle, and ring finger on the circle. This is how I played on the NES, Genesis and PS1, especially the PS1 for fighting games, like Soul Blade and Tekken, easier to pull off combos/hit all the buttons. You could make combos with R1/R2 but I never needed to.
It never bothered me before, as we didnt always have use all the buttons. For SSX, we needed to hit R1/R2, so I'd hook my thumb on the wing on the controller, and use my pointing finger to move the right analogue stick, and pinky and ringfingers for R1/R2 (tricks if iirc).
I was really hooked on SSX, as my friends and I played it constantly, trying to break each other's records, and put a lot of strain on my thumb. It got so bad I could barely hold a football, let alone the controller, as I was a QB.
I never told my coach how I got the injury lol, but a few teammates knew. I think I only missed a couple of practices throwing, but had to stop playing vids for a bit.
I think it was Timesplitters 1 that taught me how to hold the controller normally, as it was the first game I recall that used both sticks like we do now in an FPS.
My physio guy, who I had seen several times for other injuries over the years, mocked me endlessly, and deservedly so lol.
