I always see the whole "DLC was just cut content that they sold back to us" argument or similar things... Do you guys really think that if it wasn'r Paid DLC they would include it? Most of the Witcher "free" DLC is minor things that really effect nothing (and in my mind was only made free as a PR move). The VG industry is a just that, an industry and as an industry they need to make money. in the past Cut Content was Cut Content but now it has the chance to be revived as DLC. Like the HK-50 factory thing from KOTOR2, that was cut from the game, sure there are some modders that pieced the unfinished content back together and made it semi-playable but in the end it wasn't "true" content. nowadays that kind of thing can be made available later as DLC. also side note, I think that DLC's and Micro Transactions help keep the price of the games themselves down. Otherwise I wouldn't still be buying games for $60, it would be like $80-$100 for one game.
What about From Ashes? Day one DLC with rather essential content that has most of its files already in vanilla game? Or Dead Space 3 and its "you've played the game, now buy the ending"? Those definitely feel like content cut on purpose.
In the past we had expansions - some developers (Blizzard) use those even today - that naturally transformed into DLCs. They are convenient, cost effective and offer both devs and us more freedom. Also some content is cut because reasons other than to finish later and make more €$£.
$80 for a game? What about $150+ for various "Ultimate Edition" or similar? Yes, most of those are just base game and all planned DLCs, but one may look at it like "this is complete game, anything cheaper is just stripped of (mostly) optional, nonessentioal stuff". Doing what EA's doing certainly doesn't help.
But on the other hand, if publishers instead increased prices and planned DLCs either put into the shipped game or offered for free later, people would probably start sharpening pitchforks.
