In a move that'll absolutely shock anyone who's had a conversation with me about Dragon Quarter, my vote goes to BoF. Luck was on its side, this is possibly the only aspect in which I'd vote for BoF5 over ME

Wolf Kanno pretty much said all that needs to be said in the BoFV department. The regents are horrible in a good way, Bosch is battrout crazy in a good way.

On the topic of ME, I would add that while I appreciate the fact you can actually talk Saren down, beyond that I think he's a pretty generic "he's just being used" villain. And I'm not above admitting ME3 retroactively ruined Sovereign for me (don't get me wrong, I still liked ME3, but certainly not for its treatment of the reapers)
