Using subways is a struggle for most of the players in BP, commuting is long and not efficient, so as Joria said, we decided we won't rely on that sort of transportation in UC, but playing for tips is without any doubt the best to do there, so there is one. If you really want more, it is easy to upgrade lots and add it anywhere, even in dynasties and challenges, buying lots allows you to edit them and add what you want.
Katluvr, I'm glad you like open air market! Original idea wasn't OK for CAW or for challenges LOL, I'll try to remodel it into it and share in Swap Shop eventually - adding a nectar (instead of a bar), general store and relic stand would make it even better, plus fresh harvestables instead of decorative items on food stand, and some other stuff.. I'm looking forward to purchase that property in my dynasty and upgrade it
We did left several lots underdeveloped - so we can upgrade them in dynasties and in regular gameplay (like Zen garden, beach, even exclusive lounge has some rooms left). And some are just too perfect to be touched, like that amazing Pier or Central Park.
