Has there been any word on that sort of thing?
I know there's a monorailstation in Vegas, but it existing is the only info I've heard. And other than that, I haven't heard anything of the sort.
i thought they were implemented really well... I'd be surprised if they didn't use it again.
Secondary to that: I've suggested before, that this type of system could work to add a car or bike or whatever, to the current game.
Think about this: You walk outta megaton. Your rebuilt highwayman is parked in front. Selecting the car gives you the option of accessing the trunk (for cargo) or the map. Opening the map shows all your found locations. From this map you can select fast travel points. You select Rivet City.
Open load screen... when done, you are in front of Rivet City and the Highway is again parked just outta the way.
This is the only way I can really see this working in the current game. People who want the car get it... The map won't need overhauling, as you won't actively control the vehicle... Anybody who wants a unique house now has cargo and maybe a back seat to sleep in.
Thoughts?
