Physical copy of PC games....I miss these days. You could go into a local Best Buy (heck, even a GameStop) and browse through so many games on the shelf. Outside of subscribing to a gaming magazine, you didn't have an easy way to read up on game reviews so you had to rely on word of mouth or simply - the awesome box art and information provided on the game box itself.
I remember killing a solid 30-60 minutes just going through all the games on all the shelves at my local Best Buy. Looking things over, reading captions and taking in the pictures.
You get home and open the box and not only was there a game disc you installed the software from, there was a user guide or manual. Often times there'd be other things included at no extra cost (mouse pad, collectible card, world map and so on) that just added to the amazing feeling of not only owning a brand new game, but also the amazing extras you got with that you could actually find some practical use for.
You get a poster - you could hang it on your wall.
You get a mousepad - you could use it with your mouse.
You get a game map - you could use it to find your location or hang it on the wall.
You get a tree skill chart - so much easier it was trying to figure out what skills you want and how to get there as you leveled.
I miss those days. Sure, you can still find physical copies to PC games these days (they're far and few between when compared to years back), but they're generally just a disc that provides an activation key for the DRM program you need to active the game through; such as Steam or Origin. You don't usually see anything else inside the box either, other than maybe some advertisement for other games from that company or some cheap, basic game manual.
I could certainly track down a collector's edition for some games now, but they're usually 2-3x the cost over a basic copy of the game. What you get inside these collector editions aren't worth, in my opinion, the extra cost. You tend to get a disc that includes the game music, a "How it was made" disc, some little collector figure or some art-based picture book and to top it off, usually some kind of digital key-code for "extra" things in game that make your character overpowered or just look slightly different.
