I see no reason for wasteland to be crowded with cars. Does it have any relevance to F2? Woops, even the chosen one could have only 1 car and travel half of a map for it hence I see no reason for a car vendor, simply one could buy parts or find them in the wasteland.
In the Fallout world are many working cars. In the NCR are various working cars as well. Just because you don't see them in the game, doesn't mean there are none.
I see no reason to firstly impose some non-fallout reality, for example cars and a train, decrease travel speed and not enabling the ease and need for transportation.
Like above, cars exist in the fallout world. And if there are cars, there is no reason for not having trains. About the travel speed, I am too lazy to write a word now, simply because there have been written many words about it already.
I see no reason to have a possibility of people not to have the freedom to be mobile and make the game tedious to travel through.
Well, get a car. Buy one or steal one, if you like. Or wait, you want that we give every player a car on character registration? Maybe we should give them APA as well, just in case it becomes dangerous in the desert.
I see no reason for fonline to be a griefing game.
With open pvp, the game will be how it is. Ultima Online wasn't different back in time, when there have been no save-zones.
Its not "everything" its a basic thing like in-game chat.
Use radios.
Otherwise we should have quests for World Map, PipBoy, every item in FIX and running.
That's bogus. If it would be me, players wouldn't even have such stuff and all these things would be nothing else than interface elements (like it has been in the original games, except the pipboy screen).
