I always buy the CE when its available, I have got quite the collection of CEs in my man cave.
I have got some very nice ones for less than its cost to purchase this CE.
The contents do matter the most but its nice to show off a nice looking CE on your shelf.
I kind of pick and choose, I buy a lot of CEs but I don't get the CE of every game I get. I have to move and travel a lot so I don't get physical CEs unless it's a game that I consider absolutely special. I am getting the physical CE for D:OS and lots more from my KS pledge but my main focus was and is to help Larian as much as I can, it's insanely difficult to run an independent development studio and stay independent and it's much harder for them to become a big name without selling their souls to publishers(like BioWare sold their souls to EA) but I very much hope they meet the kind of success CDPR has met and they can become a huge independent name too.
