I tend to be good, occasionally too good. I side with what I think is right, but that doesn't necessarily mean I'm instantly anti whoever the "bad guy" is. I look at myself as a good mercenary, like the A-Team (except I don't always miss). I'll help if you ask and I think it's right, but I will also stand to the side and watch a camp get attacked, like when I saw traders get ambushed by CL or wandering NCR jump a CL camp. Also I'm not opposed to turning against previous allies, if the plot thickens so to speak or if you are a total [censored].
Spoiler like Boxcars, that dude is an ass and after I finish the quest he gave me, he gets on in the head.
I also tend to wait until the very last second to decide which main side I will be on haven't shot a single NCR or CL as of yet.
I tend not to be a fan of stealing in games, but I may not be able to keep that up for too much longer, there is a stack of 5 boxes of 357 just sitting on a table and I may have to grab them.
I am planning my next time through to be a kill everything that moves type guy.
