User blog comment:Lost Labyrinth/EA to go 100% digital. What does this mean for The Sims series and players?/@comment-26744861-20120705224309

Fun fact: Many devs opt for digital distribution to avoid the space limits of optical media. At the moment a dual-layered DVD can fit 8.5GB of data and a lot of games are coming in at on average 11GB nowadays. Simple - they save on DVD-ROM manufacturing costs by forcing the consumer to download a game.

As for EA...I'm suspecting their more on the greed side of things as I already said. In most cases, DRM restricts anyone from sharing a digital copy with anyone meaning instead of sharing with friends, everyone has to buy for themselves. Devs make no money from pre-owned copies either, hence why they want to go digital only. To them, it's a successful business model and they know people will give in.
