Duke Nukem 3D. I got the Sega Saturn version way back when I was a kid (yeah, because Duke was edgy and cool) and got it later way down the line for my Xbox 360.
Also got multiple copies of Street Fighter II and III because they were on various collections I got, including my SNES Classic that’s in the guest room of my parents condo, and Marvel vs Capcom on both Dreamcast and a collection for my Switch.
