Nintendo 1st Party titles are always bought physical and kept, that's pretty much it.
I do buy physical games that I intend to play through once and sell, i.e. pick it up at TESCO for like £45 and sell on eBay shortly after completing. Ideal when a £1 selling fee deal pops up, which are regular these days.
If it's an indie title then that's bought digitally for me, most of the time, as they tend to be cheaper than their physical counterparts, and come out first on digital, such as Hollow Knight (poured 50 hours into that on the Switch, my mate - a hardcore collector - wanted the physical copy, I simply couldn't wait). Also, it's easier to fire up the digital games, if I've got to get off my backside and move, I tend to not bother!
If it's a game on the PS4 that I'll play and replay again and again, I'll buy it digitally - probably by way of cheaper PSN codes off of CDKeys.
That game has been on my list since release. Not anymore...
Is it really that bad? I was hoping for some sort of SNES RPG feeling? One thing that put me off was the idea of the stories not coming together. I'm a big RPG story fan... honestly that's what put me off to begin with.
