Having the game of that size is the only excuse I accept for not releasing a physical version, but because no blu-ray will handle it, it starts darker days for game preservation. I love the fact that I will be able to undust my old PS4 in a couple of years and play GTA V without relying on the PlayStation Store. But we knew these days were counted.
Another is that there are very often below-RRP deals for games in advance, but if you buy it on launch day you'll be paying RRP.
Though I think there have been some games that let you start playing two or three days earlier.
I've been on a retro gaming binge lately because I strongly believe the constraints & limitations of older platforms yielded a better product imo.
so personally im just gonna wait a year for the PC release (a year max 2 is most likely)
