A few years ago I never traded games in, when I bought them, I kept them. My wife one day asked whether I'm ever going to re-play any of my games again, to which I replied "probably not", as I'm not a guy that easily replays games.
a Few years down the line I decided "what the hell" and started trading in all my old games, realising how much I'm saving in the end when I trade, and as I don't replay most games, what exactly is the use of holding on to these games. I started buying games, finishing them and trading them immediately, thus saving each time on a new game I wanted.
I then ended up buying a PC last year, purely for gaming. I also bought hard copies of ALL the games I wanted, seeing as I couldn't trade PC games, these things just started piling up in my game room, to an extent that it actually started irritating me.
I then started looking at Digital Copies, and as many ppl have already stated, you sometimes save between R50 - R250 on a game, the same amount you get for trading games, so it all works out the same in the ned, not just that, I don't need to drive anywhere (and I hate driving), when a game gets released on a week day it's hard for me (unless I get it delivered, which costs extra) to get to a game store and buy the game, with digital you always get to play your games on launch and never have to rush anywhere to or make a plan to go buy a game, and thus far I have never had any delay on a game I've wanted.
So;
1.) It's cost effective.
2.) It's less stress to get the game.
3.) I don't have to drive and waste petrol.
4.) I have never had any game I have downloaded go missing, get damaged or waste space.
5.) I don't have to get off my couch to take out a disc, put it back in its case, get another game, take it out, put it back in and start loading it. With a click of a mouse from the comfort of my couch I change games in a jiffy
So digital to me is better in every way
