I'm pretty sure we have discussed playing games through as good or evil before. And if we haven't, then I have to say it's something that is always in the forefront of my mind. I recently started playing Mass Effect (yes, I'm back on console! Soon to be back on Live! *gasp!*) -- and I am approaching that game with the knowledge that it is, arguably, one of the most user-affected games out there. Every decision I make has the opportunity to change the happenings and outcome of my game. And not just my game in Mass Effect, but my future game in Mass Effect 2. I can't take the stress! (Ok, I totally can. But I do way over think things.)
With these heady life-changing decisions looming around every corner, I look back on my choice in games past. I, inevitably, play "good". I can't help it. I'm the helper. In Fable 2 my character was so good they were blindingly bright and had a halo. I've never gotten to see the ugly, evil horned version... and do I want to? I've never taken the time to go back through one of these huge games and replayed as the opposite. Would it be more enjoyable to me to go through a game and fight against my every tendency to help? Would I feel as immersed, or maybe even more so? I'd be playing as a character that wouldn't be making the decisions that real-life Linz would make...and that could be wonderfully fun.
What do you play as? Do these karmic decisions affect you as much as they effect me? And have you ever gone back through and played a game in the opposite way than you did the first time? I'm going to do it...eventually. And then I'll get back to you.
