Couldn't have said it better myself.
Might purchase at some point down the road -- at a heavy discount -- but, given the large number of games that I want to play but can't due to time limitations, I'm not even sure if I'd play ME3. Sure, I want to see how the story ends but, for me at least, gameplay is parramount; to be sure, a good, engaging narrative is an essential ingredient in any great game. In my mind, however, gameplay is more important and BW's decision to have the ME gameplay shift ever closer to Gears-lite to be unfortunate. Moreover, and maybe they've refined this aspect in ME3, but the 'rpg' element they're no pushing -- the moral decision model -- needs is simplistic and lacks any sort of nuance or sophistication.
Although my recollection is slightly hazy, I seem to recall a scene from KOTOR II with Kreia wherein she chided the PC for providing aid to an indigent on the ground that this would only mean he would get robbed later. Shame that BioWare, especially seeing how they've sought to strip or simplify almost every other role-playing convention from their games, haven't further developed that concept.
