Graphics and physics engines, wich offer what i want?

[xxxxxxxxxxxxxxxx]

so what i want people to do now is ask me questions about the gameplay of the project, so i can create an FAQ gameplay article for Publishers to look at when i present them the gameplay demo. would you help create that FAQ by asking me questions on the gameplay mechanics, or on FUCE and FUIE, or on level thematics, anything that isnt related to story or characthers Please?, thankyou.

Why don't you just write a proper Game Design Document? Most Publishers will expect that anyway and you'll also need it in case you want to apply for financial support from certain institutions. (Don't know where you're from, but here in Germany you can get financial support from the Medienbord for example if you have a startup company and a promising project to present them.)

A game design document will also greatly help you in organizing your ideas, focussing on the important parts and presenting them to your team. It can also inlude an art guide and the like and is generally good to keep everybody on track and keeping the core vision of the game intact throughout the project.
