can just happen when you want them to, but when you factor an entire city or town in to the mix the instances sort of dry up. Maybe if the aspect was bottle-necked a bit like to a boarding house or something I'd be more inclined to participate.

The issue I have with the school ones is that you have to /attempt/ classes which can make things boring, or the characters just never end up going to school, In a town they could still be in the same cafe or convenience store, or just pass in the street or the park

The problem with that though is that those that are 18-25 will either have jobs or go to college, maybe even both. So in a sense they will still have a good 8 hours out of the day when they can't interact with the other people. School rps can be a boring mess but the same can be said about adult hood. xD I should know haha.

True~ But they you could interact with people at work too or just pretend jobs don't exist *Doesn't work due to anxiety*
By what I've read it will be an everyday kind of role play set in a town that is pretty much just up for interpretation as to where you want to go with it. Although that does offer freedom it also makes for a bit of a hard time to have instances where the characters will meet up and actually interact. Where as you are in a school-reason there are so many of them-interactions>
