IGN put up an interview with Casey Hudson in which they showed off some of the statistics about Mass Effect 2 that their data mining system has been picking up. They also go over some of the stuff they try to learn from it.

What They Get And Why:
IGN said:"The only data that we get are in terms of events -- little things that happen in the game," explained Hudson. "Let's say if we want to know whether players skip lines of dialogue, we can have that become a little event that gets sent up. It's all completely anonymous, so all we get is raw numbers for how many times these kinds of events occur. Then we can start getting ratios and comparing proportions and things like that. It becomes this mass of numbers, and then we have to try to figure out how we would interpret that."
This is a process that is new for BioWare with Mass Effect 2, one that Hudson hopes will aid the team in designing future games. "When we were looking at the Achievements for Mass Effect 1, that's where we realized that there are some really interesting player behaviors there that it would be nice if we could answer more questions for ourselves. [Then] we could understand what's going on and how people play our game."
"Sometimes you'll design something and think that it's going to be used in a certain way and people will use it in a completely different way. And if you didn't know that, then you would just keep making that system the same as you did before. But once you know what players like and what they don't like, based on the way that they're playing it, then you can make more of the good stuff and less of the stuff they weren't interested in."
Example Discovery:
IGN said:"Ultimately it doesn't always give you the answers, but it sometimes raises questions or gets you to ask the right questions More people played the soldier class than all of the other classes combined. If you know that, then you can start thinking about future games. Is that good? Is that a problem? Should we look at the other classes and start thinking about ways to make them selected as often as soldier? As part of asking these questions, we can design games in the future a lot better."
Example Of Reaffirming Beliefs:
IGN said:BioWare found that only 15% of conversations were skipped in Mass Effect 2, with the rate higher in non-critical moments like in the hub worlds and much lower later in the game at the climax. "If we found that 80% or 90% of the lines were being skipped, we would have to reevaluate the work that we were putting into the digital acting."
Other times, the data surprises. That happened with both how there were differences between the PC and Xbox 360 populations, as well as in regards to importing saves from Mass Effect 1. "We were surprised by how many people imported a game from Mass Effect 1 We put a lot into that feature and we could have gotten data back that said nobody was doing it. But actually more than half of players imported their save game from Mass Effect 1. That to me is quite high."
Platform Player Differences:
Source: http://pc.ign.com/articles/111/1118657p1.htmlIGN said:The average time to play through the game was 33 hours. PC gamers spent about an hour longer, while Xbox 360 players did 10% more loyalty missions on average. "In general, pretty much all of the data for the Xbox 360 version and the PC version are quite similar. One difference was the people who did certain loyalty missions on the Xbox versus the PC, which is kind of surprising. On the PC for example, people did Miranda's loyalty mission quite a bit, which is where she is trying to connect with her sister and it's more of a touchy-feely plot. Not a lot of Xbox 360 players did that one. But the Xbox 360 players did do Grunt's mission a lot more than PC players."
The PC players have the edge in dedication. Hudson claims that a lot of people played Mass Effect 2 more than once and about half of all players -- including those who rented or borrowed it -- who started played all of the way through to the end. Two players in particular on the PC played through 28 times. That's the current record. Four people on Xbox 360 played 23 times. If you're any of these people, please write in to us and tell us how you have so much spare time.
Some of these statistics are nothing more than that. As Hudson noted, there isn't any real takeaway in the differences between Xbox 360 and PC players. "Even if you know what some of these player behaviors are, is there anything you should do about it or is it just something interesting?"
