Bioware didn't QA test this game before release.
Fast forward two years later Mass Effect 3 arrives and the promise dry up like water on a hot skillet, suddenly past player choices you've made in the previous games are overridden by preset derivatives. But worst of all long time consumers and fans of this franchise who've been apart of this series since it's release in 2007 were dealt a harsh blow when starting up Mass Effect 3 for the first time only to discover that they could no longer import their personalized Shepard to the 3rd game. You're force to rebuild your character completely from scratch and to top it off the enhancements and features that was apart of the character creation in the previous two games are gone, so it's impossible to replicate your original Shepard.
I don't know if this was intentional or if this is an oversight on Bioware's part but it completely ruins the game for me and many others who were anxiously waiting to continue the story to complete the saga after supporting this series for so long. But not being able to import your own creation which was the core part of the original series is a huge slap in the face to fans and all around who are unaware of this problem and are interested in playing Mass Effect.
