Why did we choose the title "Design With Play"?
It's probably semantics. We feel strongly that not only do we want to encourage play through good design (i.e. design for play), we want play to be intrinsic within the process as well (design WITH play). If we're constantly designing with play in our minds, we hope we run a higher chance of being successful.
Get it? If not... that's okay. Suffice it to say our goal is to treat play as not just an event, but an intrinsic part of who we are... children or not!
