No way in hell is a director going to leak a prototype, especially not to some random guy on the internet.

Enough about making theories crafted from nowhere, enough trying make "plans" from absolutely nothing. If you can't decide what engine to use and expect others to do a load of unpaid work for you, especially for a franchise the JJ2 community barely has interest/knowledge in, you are not fit for the ambition, and in the wrong place. For example, if I wanted to post about making a Sonic fangame, it would not be this forum, because it's NOT where the fanbase resides!

There is absolutely no point in making a game work only for a super outdated console. No one cares about "authenticity" when it's an unreleased game.

And yes, being overly ambitious about your ideas applies to the Jazz one as well. If you can't do anything competently and expect others to do all the work for you..it's not your project. A simple HD remake doesn't need a director.
