Not all ideas are worth sharing, sometimes they're even horrible... But there's never a bad idea, and as you'll see much of what was scrapped found its way into other aspects of the concepts I shared. This page is largely still a work in progress, but there is some information.
Currently, this list is titles only. This page is a work in progress and will be expanded on at a later date.
