Ophi, I know how you feel about Mass Effect and Dragon Age. Those kinds of big games are really hard to get back into if you play them once, because you've invested so much.
I know people who play them over and over and I don't understand it at all. Earlier this year, my hard drive failed and I lost savegames for ME/ME2 and Origins; I liked ME2 enough that I replayed ME and am now stalled halfway through my second ME2 playthrough, but I'd spent over 50 hours on my Origins character that I really didn't want to trudge through again.
