Nothing against Microsoft / Xbox, but for me the 360 generation AAA titles like Halo and Gears of War kinda peaked at the time, and I haven't felt the need to upgrade and play the sequels.
PlayStation exclusives always held a bit more interest for me too - Uncharted, Horizon Zero Dawn, Spider-Man, God of War - to name some of the best titles.
That said - I never got to play / replay the legendary Banjo Kazooie games since they went Xbox exclusive!
Frankly I just can’t see myself ever spending £70 on a game
Game prices for PS and Xbox always consistently and significantly drop in my experience, I wouldn't get a new release for either system unless I
really wanted to play it.
Nintendo AAA titles on the other hand hold their value like gold bullion.
