Slightly double-posting I guess, but.. I just watched
http://penny-arcade.com/patv/episode/mass-effect-3-dlc (Yeah, I know I'm a few weeks old on that).. I'd suggest watching it too if you don't already watch Extra Credits. Anyways, one thing they said resonated with me... that DLC sales fall off dramatically over a short period of time.
This explains a lot of why they had the season pass available right off the bat.. the hopes was people would buy it and then play the DLC as it came out. Then the DLC flood they odo otherwise feels like a two-pronged attempt. One is to add stuff people who are replaying the new DLC stuff that just came out (that they bought when the game came out) or even people who just bought the game then will see "Aha! DLC!" and buy it.. and two is to saturate the market with volume of content. They know they're going to have severely reduced sales.. so in turn they throw out as much DLC that's cheap for them to produce (like, say, a reskin of a vehicle, or a modified tweak and animation, or cheat codes, or what) in the hopes that with the reduced numbers of people who buyt the DLC, they'll still get some money out of it by having such a massive quantity that even 1% of the DLC bought across owners is still a sizable chunk of cash. Considering how easy some of this non-story/mission DLC is to make, it probably takes the staff very very little time to make.. so they will likely keep pumping it out for a long while, even as they work on other stuff. In other words, expect this sort of stuff all but until the release of the upcoming dlc/expansion-pack/semi-sequel/whatever-the-hell-it-is, and then DLC after that if possible.. right up until they finally shift 100% of their focus on Saints Row 4. Even AFTER most of the team has moved on, it's a sufficiently small effort for them to do a (sloppy) reskin of a character and stuff it as a model then sell it as a DLC, so they can tell some random worker at Volition to take a few moments off designing that new mook in the upcoming game to do that, and they can have it done in a day or so.
The other thing is if this sort of tactic works, expect the new SR4 to play very much the same. It's.. like they're trying to combine a full retail price game with a free-to-play microtransaction model. Interesting idea.. if it was PC only I can see them charging far cheaper for the game and living on a lot of DLC.. and if the game was continually played it'd work (let's face it, how many of even the modders here continually
play the game multiple times, not just to test a mod but to
play it?).. but I don't expect this to work more than just the spam to raise the size of your small percentage tactics.
