I recommend at least doing Caesar's version of the main quest until he'll let you ask some real questions. He has some really interesting dialogue, and it's fun to find all the ways you can piss him off.hyzaku said:As for talking with the legion, I actually hate them. Genuinely, I detest the Legion and their attitudes towards many things. I have yet to feel any desire to not murder Ceaser and his entire lot. I may work to it at some point, just to see the content.
Also, the endgame is significantly different (I'd say harder) for Caesar's Legion compared to the other factions.
