The first disc covers the beginning and end of the game, while the second handles the middle portions. Eliminates ”multiple” disc swaps.
”The decision was made due to the nature of having to go to two discs for what is a non-linear game and fitting the right amount of content onto each of the discs,” BioWare’s Jessie Houston spilled to IGN. The ‘middle’ occupies the free-roaming of the galaxy.
”Players will start with Disc 1 for the introduction and early level choices, then go through a funnel level of sorts, where they will need to switch to Disc 2,” they said.
”From there they will play the middle portion of the game, which is mostly on Disc 2. Then after another funnel point in the story they’ll go back to Disc 1.” This is to alleviate annoyance, and nothing to do with piracy measures. ”This way players won’t have to swap their discs multiple times during the middle of the game.”
Oddly, if users opt to install Mass Effect 2 to their Xbox 360 HDD you’re still required to make the disc swap. Hopefully BioWare will work with Microsoft to remove that. Which copy will you be going with - Xbox 360 or PC? Still no chance it seems of a PS3 outing.
