Mine was Unreal 2 for PC when I was 16. My dad used to bought games for me, so I didn't need to buy other games really. The console of my childhood is a NES that I still have, but can't use anymore because the power supply got lost. Then my older brother bought a PC, so I started to play exclusively on PC
But speaking about games that I've bought with my own pocket money (earned from working), my first console was a Xbox One S with Forza Horizon 3, in 2017.
