I'd have a tough time, and go on a crazy adventure... last time I played was on a new character (with a bunch of new mods installed) who is going to join the Followers of the Apocalypse... he's currently level 4 and armed with a recharger pistol..
Any of my other three characters, though... I'd languish in my riches as the owner of the Lucky 38 (or, in one case, Mr. House's top lieutenant)... surrounded by my friends.
