@ Tot: I'm aware of what I said, and then Mass Effect 3's ending comes along and shows you just how bad an ending can get that it ends up turning the journey sour... that is for a rerun. I cherish my one and only journey through the Mass Effect trilogy until that ending... however, because of that ending, I find that I can't go through that journey again to take all of those different choices I never took. Because of that ending, once is enough for me. No more.
And that is why BioWare failed. They did nothing to spur the audience on to get excited about replaying the games all over again, it wasn't just a great missed opportunity, they ended up evoking the opposite reaction from many people with the way things turned out.
