i have done many things on fallout new vegas and i am getting bord can anyone name some quests or things to do i have finished the game
with all factions

If you're playing on a PC get the http://www.newvegasnexus.com/downloads/file.php?id=38719 mod.

I'm not on the pc I'm on the xbo360

Get the weakest gun you have with about 100 bullets and the weakest armor/clothes you have then take 10 stims (food and water if you have hardcoe on) and go to the Jacobstown and travel from there on foot to cottonwood cove only buying from places you encounter on your IMMEDIATE route.

Ok I'll try it anything else

in cl recruit armour kill eliminate every NCR camp, base, or outpost after the vets and heavies show up. On very hard hardcoe.......

complete the game with a different route.

Yep. Just create a new character and start over again. I play with my third char now, and still discover new quests/ways to do a quest.
