What do we need?

[KyleMassacre]

there has been some talk recently about the engine not being ready to create a fully functional game to play. So my question to you guys is:
What do we need to have?
Rules for posting here:

Can we have some nice formatting to make it easier to read? I am not asking for MLA but maybe some ordered and in ordered lists like:

1. Module Title
   • Module description here
     1. Some key points/features

Also the modules need to be key for a game to run. I'm not looking for custom, game, or genre specific modules. So let's hear the ideas come in

I think the engine is functional for a complete game, it just need more layout of the CSS. The layout is the same for every theme.
