"Real caravans" are in plans since looong, looong time - it was said in most of threads about caravans, so it's nothing new.
Poor alts.
I agree with this... who cares if someones fairly unused taxi alt becomes obsolete... new characters who are having a tough time traveling may have a chance at finding a caravan and joining them. It would make the game less harsh for new players, and would leave it relatively UNCHANGED at late game.
Taxi alts are used for teamwork anyway, how often does anyone see a taxi alt, LOOKING FOR WORK? Taxi's are usually organized with their own factions or friends, and aren't meant for wandering new wastelanders.
This idea is great, and would really help out the poor retention rate this game has. If we can keep new players interested, (and this is DEFINITELY one of the ways to do it) than we should!
I don't see how this could be a bad thing at all... New players would still need caps or something to pay for the caravan I'd assume, right?
