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."

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.
