Give me the faction you like the most (of the main 3) and tell me why?
For me its the NCR because you get the emergency 2 way radio that calls in support for yourself... also I live in California! For The New California Republic!

The Legion because I really do not want to get them mad. Although I am friendly with NCR because if I have the caps they will repair my gear to perfection.

So far the NCR. While I agree with the Legions dealing with Nipton (odds are if I could I would have killed them all also), I did not agree with there tactics. Also the further I get along the story the more they are just plane vile.

I have a feeling I will switch to Mr. House when I bump into it as all it seems to be he wants to do is secure what he holds.

I am not fond of the NCR as even though they are on oppisite sides of the coin with Ceaser's Legion... they are still made of the same coin. Both have the same goals to conqure the area not really help it in any way. I can't help but feel that the area was better off before these two goons showed up.

However if I find out Mr. House is a duche like the other two I may just try to kill 'em all...

(first play through... I always tend to play it as if it was me. After that I will try out all the factions)
