Playing the Mass Effect trilogy a few years ago was one of the highlights of my gaming life.
The only negative of the series for me was the opening 3 hours of part one, where you are running around the Citadel.
I was really taken with ME1 and ME2, but I never got around to playing ME3, firstly with the uproar at the story (Which I avoided reading about, and still have, for spoilers, but I am aware of the wizard jist)...
THen there was news of a re-cut or DLC to slightly bring fans around.... and I never quite felt like playing.
This may inspire me if I have some extended time to do 1 - 3.... it sounds awesome to do, and to really immerse yourself. Not sure I'll ever get that kind of time though.
