There will be a target rang with live objectives (definetively better than in RR and in MZ). Of course, if it isn't a simulation, it the targets can be "captured enemies and creatures", like in PL. And about the Protectron saying "Welcome to the Bunker 72", you could use the part of the dialogue with the Protectron outside Megaton, when he says Enter/Come on or something that means "Enter" (sorry, but I play in spanish (altough it's maybe impossible with FOOK, but no problem) and I don't know the exactly words, in spanish is "Tira pa' dentro") the first time you arrive to Megaton, after exiting the Vault 101 and when the Megaton DOrrs are opened, so maybe the this part of the Wellcome will change dependent of the language, of course only if this part of the dialoge has an audio archive for it alone.
