Not sure that's going to work particularly well, I found the opening of the game to be the weakest part.

I did manage to finish it, and it actually ends quite well. The final mission isn't magnificent in itself, but they do that cool Mass Effect thing of getting everyone you'd become friendly with to turn up and help out and it feels pretty epic. I definitely found myself interested in a second game set in this world, with the obvious proviso that they actually do it properly and don't fill it up with tedious grind.

If you are a big Mass Effect fan and wait for it to get proper cheap and go into it with low expectations (and skip most of the sidequests), you'll find stuff to like. Though you are playing the first part of a trilogy we are clearly never going to see now, so it might be a pointless exercise.
