I find the Bioware choices quite forced and artificial, don't get me wrong, they are imho the best games out there that aren't TES or Fallout, but it seems like do some stuff, major plot point, make choice, do some stuff, major plot point, do some stuff. I prefer the few choices but more free form feel of TES, where you don't feel so funneled. Having said that, not joining the DB was a proper moral choice with consequences ( role play a decent, morally good or neutral character, miss a big part of the game ), and remember these guys gave you the choice to nuke a town or not. Nothing against moral choices, they are a fantastic idea which would add to the game, just rather do without and play good old TES than have a huge main plot with major morality crises strung along it.
