I have a strict, self-imposed policy of never paying more than £12.99 for a digital game. I consider digital data effectively worthless and I just won't pay any serious amount for it. So the last games I bought on disc were recent, GTAV and Project Cars. The big full colour map and the box/discs made the GTAV set well worth the money. Nothing could make Project Cars be worth the money I paid for it... sadly.
Music I buy on CD, films I buy on Blu Ray, TV shows I buy on DVD (as you can see from the attached image which is just the shelf over my computer) The bottom right of the picture is import music from Japan and some of them are magnificent physical items. Full colour hardback photobooks, group member photocards, signed photocards etc... They cost about four times the price of the digital album, take three weeks to get here but I wouldn't buy them any other way.
Games have always been bought on whatever medium they come on. I still have my boxed copies of Lords of Midnight and Doomdark's Revenge on cassette for the Speccy. A lot of my philosophy is guided by the fact I have been a developer and the satisfaction of holding that completed game is priceless. As such, you appreciate the value of the same thing from other developers.
I suppose it's a bit like the Gold discs music artists get, whilst not as valuable as them, my Bosconian cassette is an important part of my development past. There's something satisfying about pulling the manual out of the box, turning to the credits page and seeing your name. Digital just doesn't give me that buzz.
Even though I have a limit on what I will pay for a digital game, I don't have any similar limits when it comes to physical games... within reason. I recently paid about £53 for DOA Xtreme 3 on the PS4 and was happy with that. No Man's Sky will be a PS4 physical purchase, as will The Last Guardian, if it gets released before I die that is.
That's just my take on the whole thing, sorry if it was a bit of a ramble.
