I'm obsessed with this game, and its sequel. It is one of the most intelligently written, beautifully crafted series I have ever encountered, including major motion pictures. Granted, I have always gone the heroic, or Paragon, route, because I find the relationships that you develop with your team members, allies, and even opponents are much richer when you choose honorable and noble interactions. I don't know what sorts of doors the Renegade path opens in ME1, although I know that going Renegade in ME2 as a male Shepard opens the door to an angry, casual sexual encounter with a psychologically damaged female crew member. Others have noted correctly that the violence in this game is minimal in comparison with other best-selling M-games--my teenage brothers are intense gamers, and ME1 did not draw them in at all, although they love the sequel, which contains more violence, harder language, and more risque content. I have always played as FemShep (female Shepard), and have never pursued the same-sex option, because I was more interested in Lt. Alenko. The relationship you build with Kaidan culminates in sex, as well, and you see a brief shot of Shepard's naked rear in the cutscene (nothing else, though, except Kaidan's somewhat clumsily animated pecs). It's nothing a kid wouldn't see in a PG-13 movie, but the encounter is more powerful to the game-player than the move-watcher, since it seems like you ARE Shepard, after spending so much time in his/her head.
