I lost my savegames in a hard drive crash a couple of months back and I did consider playing through ME1 again to get some benefits and freshen up on the story.
Guess what? I couldn't bring myself to do it, the first one simply didn't do a good enough job at keeping me intrigued and excited (it had me bored to tears even, at times, especially the drab sidequests and immense loading times).
I'm currently playing ME2 on the PC and can't help but feel disappointed yet again, unfortunately.
Maybe I'll do them both in one run some day, to get the full story, the launch of the third one is probably as good an incentive as any but I do dread the day I'll be climbing up into the Mako again.
