I prefer both Physical and Download titles, let me explain my reasons....
If it comes to Phyisical I rather have Cartridges, so we're talking about mostly retro gaming, and as an exception Nintendo 3DS and so on...
But I prefer digital downloads for everything that came out on CD / DVD / Bluray for the simple reason of when you collect those, there's something called "CD rot"....
After 25 years of using a CD format style media, it stops working.... so you need to throw it away or keep it as a gimmick you can"'t use anymore...
That's where digital downloads might be handy, it's always available, and I'm assuming, by the time the digital download is unavailable, something else will be there in the future...
