I got everything I could, no order of importance:
1. Nintendo Switch (sep-2017): Main use as Portable beast. Nintendo games cannot be replaced by other stuff. I avoid multiplat titles like the plague though. Feels good collecting physical titles, despite they are almost never on a discount.
2. PC - 3700X, RTX3080, 1440p 144hz monitor (dec-2020): Mainly for competitive FPS, well optimized PC ports, older titles. Some double dips, like RDR2 for instance. Buy games with real discounts. DX12 games with shader compilation problems makes me think more before buying something.
3. Xbox Series X (jan-2021): Mainly for multiplatform titles, finding out new stuff on Gamepass. Ninja Gaiden Black machine. Mostly Digital.
4: PS5 (feb-2021): Mainly used for exclusive Sony stuff. Also physical titles being sold way cheaper than Xbox (Germany).
5: Steam Deck 512GB (mar-2022): The real MVP… I am in a long, long trip. Having access to my Steam Library plus tons of emulators is simply bliss. Battery life while Ok, could be better. Backlog killer.
