Fallout: New Vegas - Preview @ ResumePlay

Fallout: New Vegas has been previewed at ResumePlay.  Here's a snip:

As you go about your business in New Vegas you come across a variety of factions that claim ownership to a specific territory. You will quickly come to know factions like the New California Republic, The Brotherhood of Steel, and Caesar’s Legion. Reputation returns in this title after its absence in Fallout 3.  Your availability of dialogue options are based on your reputation, karma and skill.  So, this time around your skill has a substantial effect on your conversation choices. Your success in conversation depends on it, and isn’t based on sheer chance like you saw in Fallout 3. Depending on whom you kill or befriend and what side you take the notoriety system will take note and some people will want you dead while others will seek to aid and pay tribute to you.
