I'm gonna say,
I started playing Bioware game with Dragon Age. I freakin loved that game, so even though sci-fi wasn't as interesting to me as a genre, I played Mass Effect. Didn't love it as much as Dragon Age, but enough to play Mass Effect 2, and I think they're both awesome games. Even tho I've never been much for shooters - hell, I suck at them - the gameplay was still fun. The thing that puts Dragon Age above Mass Effect for me, is a) the fantasy setting over the sci-fi setting, and

the crazy amount of choices and customization there is,
So just this last week, I bought KoTOR and started playing that. And while I'm enjoying it, I can say I have no issues with Bioware games becoming more action-rpg. In fact, I'm glad they are. Combat in KoTOR is too un-involved. Yes, I would rather button mash and have fast paced action then just watch the computer make attack rolls for me over and over. I get enough attack rolls doing table top rpgs - and at least then I actually get to roll the dice.
